I've killed my colleagues' characters during RPG session, now they won't talk to me

however I find it childish

All parties involved here are acting like children. From their point of view you deliberately ruined what was or should have been a long-running game on a whim and you evidently failed to even apologise for doing so. Your colleagues are also behaving somewhat inappropriately if they are indeed freezing you out of all social interaction as the professional thing is to treat colleagues professionally and amicably, even if you don't like or actively dislike them. But at the same time they aren't required to include you in their social circle or friend group and you can't demand that they do.

So that being said, you screwed up. You really screwed up. And the reason you're being ostracised is almost certainly the fact that you don't recognise that you screwed up and haven't apologised for doing so. And that's a Big Problem. While I'd rather not get into the details of your actions in the context of the game as the question David linked does that well, it's easy enough to summarise. You were invited to join a cooperative game that's been in progress for at least ten hours and in which the players, your colleagues, were heavily invested both emotionally and time-wise. And then you destroyed it all. And several of them probably hate you for it.

And why wouldn't they? You stabbed them in the back, perhaps even literally, from the first moment where they really included you in the group and since you've only been with the company for a few months that's really all they know of you. So in their minds you are at best "Not A Very Nice Person". For the same reason that you need to be on your best and most productive behaviour during your first months at a company, the same goes for how you treat your colleagues. And pissing people off is not a great way to do so.

So what you do now is apologise. Profusely. How you do so is up to you, but the points you want to hit is that you got too caught up in your character and regret ruining the game for them. Say that you shouldn't have pulled a stunt like that in a new gaming group without discussing it in the group. You'll probably want to acknowledge that it took you a while to realise that you were out of line.

Hopefully that will be enough to get them to talk to you again and you can begin repairing the relationships at work. I certainly don't believe that you've ruined any chance of getting along with your colleagues. With some time you can probably even ask to rejoin their leisure activities as long as you make it clear that you won't be repeating this incident.

To be entirely clear, I'm coming at you strongly here because you failed to recognise that this was A Big Deal to your colleagues and a honest mea culpa is what you need to show that you regret how things turned out and that you now realise that this wasn't a great move. But as I mentioned both parties share blame here. The correct response from the group or the DM (the person running the game) would have been to either stop you or, as you mentioned, roll the storyline back to before you turned traitor. In both cases you'd have had a conversation on how the group that you just joined runs its games and what is and isn't okay. The same page tool was mentioned in the comments and is one way of approaching this. If you follow that link you'll find that it's listed under the "group dynamics" tag and that concept is just as important at work. You need to remember when you're socialising with colleagues, even in very informal settings, that there will always be a professional boundary that you need to be aware of and that the consequences for crossing it can be higher than they would be among friends or acquaintances.

This is known in the gaming community as "chaotic evil stupid". It's not an uncommon mistake for beginning players, but it always has the effect of getting them kicked out of the gaming group in a hurry, usually with a lot of hurt feelings. (Getting your own character killed in an entertaining manner may be an exception.)

Players have spent a lot of time and effort developing these characters. You committed an unjustified act of vandalism.

This is basic gaming etiquette. You made it worse by dropping that turd in a room full of people much less likely to forgive you, and whom you need to continue to work with.

As others have said: All you can do is make clear that you now understand just how rude your action was -- the preceding paragraph is not exaggerating -- and plead that you were a clueless newbie, playing for the first time, and got caught up in the concept of roleplay without considering that this is, first and foremost, a cooperative storytelling game. If you can convince them of that, this may blow over. If not, well, folks will put it in perspective eventually but your judgement -- at least regarding social situations, but possibly generally -- may be considered questionable for some time.

For more advice, ask on a roleplaying game forum. This isn't specific to the Workplace.

The situation seems surreal to me as firstly it was not my intention to upset anyone, and secondly I find it really hard to believe that killing somebody's fictional character, can lead to such behavior, especially since they can rollback the entire campaign if they want to! My guess is that they are trying to "punish" me for doing what I did, however I find it childish.

You have proven to be a bad sport and ruined everyone's fun for your own gain. Why would they continue to be your buddies and hang out with you? It probably was a good group before you came up and right now it is again. It's not a punishment, it's the logical consequence of what you did.

My question is: What would be the best way to repair my work relations with my colleagues after such incident?

The best way would be to understand what you did wrong and apologize for it. Explain that it will never happen again and mean it. I think the first part is very important, I don't get the impression that you fully understand what you did. It's not about fictional characters or rolling dice. It's about ruining other (real) people's fun on their free evening.

A lot of answers have focussed on the game, but I think that's the least important part. Where you really dropped the ball is here:

At this point I noticed while some of my friends were shocked/surprised by the situation (but still having fun), the rest was clearly disgusted as what just happened meant creating new characters, starting new story etc.

When you are at a social event, any social event, and you notice that the people you are with are reacting with genuine disgust to what you're doing, there is a problem. A very big problem. The moment you notice that attitude towards you, you have to stop whatever you're doing and ask these people "I'm sorry, I seem to have said/done something wrong. What did I do?".

And then, at the very least, apologise for what you did and ask how to continue from here. If you had done this, most likely the response would have been "This kind of behavior is not acceptable in our games", at which point you could've maybe rolled it back, or at least come up with a solution. And the night would've ended fine.

But you ignored their negative feelings. Those people most likely left what should've been a fun and relaxed evening event feeling very poorly. You still seem to be unsure of what you did wrong, so probably you have not apologised to them despite this being days ago. So for the past few days, these people may have been feeling bad, about something you did, and you never even acknowledged that you caused them grief. Even though you knew. (And perhaps they are even aware that you know)

It is likely that your failure to acknowledge that you did something bad and ruined their fun weighs much heavier than any characters you killed. Like you said; the story can be rolled back, the characters can be restored. But the negative experience of you ruining their night of fun and games and then not acknowledging it or apologizing for it will not fade so easily.

What's going through their heads now is probably not "Anon killed my Elf Wizard", it's "Anon ruined my evening and he doesn't even care that he ruined it."

As for what you should do now: apologize to them. Apologize for ruining the game for them. Apologize for ruining their fun during game night. And apologize for not realizing it was bothering them at that time.

Apologize immediately.

Try to convince them that you understood what you did and why it was wrong.

Leaving the game mechanics issue aside (that would be better suited on other SE sites), the result of your actions is that you came out like an unsportive and unfriendly person, that ruined their fun on purpose.

Engaging in out of work activities with your colleagues may be fun, but you have to be sure that everyone is actually enjoying it. Bad mood and feelings generated outside the workplace will surely spill in.

The fact you consider the causes or the reaction childish doesn't mean your coworkers do too.
If they reacted isolating and ignoring you, it means that from their point of view you did a very mean thing, and need to act immediatly before their behavior becomes permanent.

As an aside on D&D specifically, you joined the campaing and created your character in about an hour. Their characters were alive for a few more session (so about one month, maybe more).

You don't exactly know how much time they spend refining their build and reading manuals, or working on their background, but maybe the characters you killed had a book worth of backstory and were planned to last for years, realizing their creator's "dreams" and becoming epic and powerful.

Surely if you killed one of my characters as the new guy, and just for the sake of it, I would not take it kindly and would probably react the same way, if not worse.

Games have both written and unwritten rules.

Each time a group of people play a game, they end up agreeing on unwritten and often unspoken rules and assumptions about the game.

Some games of D&D involve backstabbing and inter-party conflict and chaotic stupid characters. Others don't.

You appear to have violated the unwritten rules of the game you where in. The fact that this came as a surprise and you think you did nothing wrong means you may not be aware that strong unwritten rules underly many kinds of group recreation.

To the other players, you where someone new to a group activity, who in the first time they showed up gleefully violated the unwritten rules of their group activity, and did not demonstrate any remorse for doing so.

To you, this was just something you did "in the game". To others, this could reflect an inability to pick up on unwritten rules and follow them to maximize the enjoyment of everyone in a social group.

They appear to have responded by avoiding you in the short term. You seem to have only picked up on this response many days later, which is further evidence you are not picking up on non-explicit social signals.

Interacting with someone who doesn't pick up on non-explicit social signals is extremely tiring and often not fun. So at this point, you are being treated as someone who they shouldn't share their group social events with, because they cannot trust you not to break them. They have reasonable and growing evidence that you are a risk, and little evidence to the contrary.

Building social groups is work, and damaging them is easy.

So, how can you fix this. The first thing you can do is actually realize what you did wasn't good. You entered into a new social dynamic, and proceeded to break it. You may not have intended to, but you don't act with care in this new social dynamic.

When you entire a new social activity with a group, you should act relatively passively and learn what the rules of this group is. You shouldn't proceed to do something you haven't seen anyone else do, especially if it could be considered aggressive or harmful in any context.

First, internalize your error. Look over your life, and see other situations where "through no fault of your own" the same thing happened.

Now that you understand that, go and apologize. Don't use these complex words; talk concretely about what you did, and apologize for what you did in that game. State it wasn't appropriate. Don't justify your action with anything as complex as this answer; that looks like excusing yourself.

State you where a real idiot. Individually to each person. In a context where they aren't trapped or cornered and forced to interact with you. Without grandstanding.

After you have apologized, see if things thaw. After a day or so, take initiative and ask some of them to do something social via the old chat channel.

The problem isn't what you did; the problem is what you did in the context you did it.

@Lillenthal has a very good answer, but I thought I'd contribute a slightly different perspective to the issue.

The issue doesn't have anything specifically to do with the RPG (and I say this as a mod on RPG.SE and a tech manager). It could have been socially inappropriate behavior in any kind of pastime. The group could have gone out to a happy hour and you could have gotten drunk and hostile. They could have been playing a soccer game for 2 hours, and at the end you deliberately scored an own goal and shrieked "woot!" at them. You behaved in a way that makes them concerned about whether you are trustworthy or not.

If this were just a friend group, this would actually be less of a big deal. But when "playing" with co-workers, there is an additional layer of dynamic you seem to be unaware of. The work doesn't ever completely go away. You are continuously interpreted on two levels, the social level and the work level. This can be difficult, which is why some people don't socialize with co-workers (and why dating is forbidden at some workplaces).

So their concerns about your trustworthiness go beyond the D&D game, they slop over into work, where you definitely want people to be reliable and not backstabbing. They now have the very real concern "Hmm, if things were to go bad and there were to be layoffs or something, this guy seems like the 'kind of person' who would roll over on someone else to keep his job/get a promotion/etc."

In the RPG world, there's "different playstyles" and it's not objectively wrong to play CE characters and player-kill and all that. But in the real world, it's definitely wrong for you to be the first person to go there, especially when you're new. Just like you probably don't want to be the first person to whip off your pants at the company Christmas party. By doing that (either thing), you've raised a big red flag that says "Poor Judgement Shown Here." You've shown poor social judgement, both from deviating from their norms and especially for not apologizing and not understanding what you did wrong. And no one wants to spend their fun time with Poor Judgement Guy - or work with him on a project, or rely on him to peer review your code, etc. (Unless they are also Poor Judgement Guys, in which case your workplace begins to resemble an episode of Workaholics.)

What to do? Apologizing is good. But that won't build back the trust, you need to do that yourself by not acting like a freak, both in pure work context and in social context with them. Be kind, reliable, and show good judgement and they'll accept you again.

Is this "fair"? That's a childish question that doesn't matter in the real world. People judge others on early impressions and like to think they can intuit a lot about their personality and likely end in life based on notable interactions with them. Given what you did, the others are all thinking their own variations of this. "I hope he doesn't come in and shoot up the office," one is only half-joking to another right now. Is that a ridiculous extension of something that happened in an elfgame? Maybe. But that's the situation you're in.

As you work yourself out of this situation, I hope it's a learning experience for future work/social interactions. Unless your workplace is a biker gang, being the first one to break social norms is not a desirable trait. You don't have to stop if you perceive that as "the Man keeping you down;" you can get away with it if you are a) very charismatic and/or b) you learn how to read the room better.

I would suggest maybe apologising to the group. Although it fit into your character, it has still ruined their fun. People build emotional attachments to their characters (and the backstories they come up with, peculiar character traits etc), so for "a new guy" to come in and kill all of that is bound to annoy/upset them.

So with that in mind, it's not necessarily a surprise to see this has spilled over into general social interactions, and not just the D&D session.

So I would suggest apologising for killing their characters. Call it a momentary lapse in judgement/misjudgement of the situation etc. You may not get the invite to play again for a while (if, at all), but it will at least acknowledge that you didn't mean to hurt their feelings with regards to killing their characters.

And in the future, I wouldn't say be careful, just maybe don't play "chaotic evil" to that degree if you play again with them. For example, maybe taking an item from them if the situation arises, but not killing them off.

Understanding the RPG aspect, this question can be simplified to "I offended my coworkers now they don't like me anymore, what do I do?".

• Figure out exactly how and why you offended them. Don't stop at "because they're childish".
• Once you realize what your actual mistake was, apologize, and don't repeat the mistake.

Do not apologize before you understand and accept the mistake.

What was your mistake? They were playing a game, with the purpose of having fun. They invited you so you could join in on the fun. You did something which you should know is extremely not fun for some people (killing the campaign on purpose), without first figuring out if it's fun for the people you were playing with. The problem isn't your character backstabbing their characters, it's you backstabbing them, by accepting their invitation and then ruining their fun.

As other's have said, you need to apologize and show that it was an honest misunderstanding of RPG games and show that it won't happen again and doesn't reflect who you are.

The point that I think most of the other answers have missed, or failed to highlight enough, is that while, in theory an RPG means you are taking actions for a character rather than as yourself, it is still a meta-game. You are still a player and you are still playing with other players. How you play your character, even if they have traits that you don't, reflects on you since your actions also impact players in real life.

Certainly your case of this isn't the worst by any means that I've seen, but I've seen otherwise reasonable people harass other players to know end under the justification that their character is a "bad guy", resulting in a total disconnect from realizing their attempt at fun is ruining the experience of other players.

The problem isn't that your character killed their characters, as you rightly point out, if that was the issue, they can simply roll back. The problem is that you, as a person, were having fun by ruining theirs. You failed to consider how your in-game, in-character actions would impact those you were playing with personally. In another group that is into more brutal gameplay, your in-character actions would be fine, but that's because you would be playing with a group of people who like that instead of going where the rules allow, but the desire of the community you are playing in does not.

It's very important in any game with adversarial action to consider the impact on other players first and then on how it fits your role play. Playing a make-believe evil toon doesn't relieve you of your responsibilities to be a good player to those around you in real life.

If you can focus on making it clear that this was an accident, that you didn't see how it would impact them personally and do something nice for them to demonstrate that you are sorry for the impact it had, you can probably get over it fine. It's a bad first impression, but I doubt it's anything anyone would really hold against you long term as long as it is just a mistake and not a deeper underlying behavioral issue.
