If you're playing a game like Guild Wars it's probably because you are already entertained by fantasy violence and skulduggery. I actually think this is a healthy thing, insofar as it shows the character getting punished within the context of the game mechanics. Just blocking the account or whatever is arguably rather like the way we treat people with prison - sending them away to a place where we don't have to look at the consequences. If videogames do inform attitudes and behavior - and I find that thesis questionable - than doing the punishment out of sight arguably teaches people that the appropriate response to social problems is to make the offending parties disappear.
