Dungeon Master needing a jerry springer's advice

[Coplantor]

Point out to him that the rest of you are there to play a game of adventurers fighting monsters and exploring dungeons, not murderous interpersonal conflict. If he wants to play a different game, he can do so, but not during yours.

Suggest that if he's got a hankering for internecine conflict, he could run or join a Paranoia or World of Darkness game.

Well, he DOES want to play vampire the masquerade.
