This is what happens in role playing games when the Game Master gets utterly fed up with the players: he kills them all spectacularly. Precisely what drives a GM to this extreme varies. Perhaps somebody was a Rules Lawyer once too often. Perhaps the gaming group mocked his plotting skills a bit too much. The players might have spent all their time going everywhere but where the plot wants them to. Maybe the group consisted entirely of Munchkins. Maybe they didn't like that "totally awesome" GMPC as much as the GM did and tried to kill him in his sleep. Or maybe the players are just Too Dumb to Live. Or maybe, just maybe, the GM is a sadistic bastard who's determined to see the players fail at any cost.
