You misunderstand. It is inherently an out-of-game problem--a bad player. That requires an out of game solution. No one is disputing the idea that a jerk makes jerk moves in game, but that the best solution is not to kill the jerk’s character. Instead the best solution is to talk to the jerk, and if that fails, drop the jerk from the game. Killing a character of a player you dislike is a textbook case study of passive-aggressive behavior. Passive aggression does not solve problems. Indeed, it compounds them. Because now you have a jerk player who knows that you’re out to get him personally, which leaves you with not only a jerk, but an angry jerk. Not only that, but he has a right to be angry.
It’s the same idea as teacher/student problems. If you are a teacher and you have a student who is just an utter (Gibbering Mouther Ate Your Word!), you don’t have any right to fail him provided he does the work. You can discipline him, give him detention, call his parents, etc, but that cannot be allowed to affect his grades. If an (Gibbering Mouther Ate Your Word!) does A quality work, he deserves an A, regardless of how much of an (Gibbering Mouther Ate Your Word!) he is.
