First of all, I'm Victor Frankenstein.
My victory condition is to gather four corpses, and then have my abomination kill two players.
Only problem is I can't actually gather Mafia corpses, but there isn't anything preventing me from killing them for my victory condition.
Depending on how many mafia/neutral players are in game I might be forced to kill off some town members, but I would have to do so in a way that prevents the game from ending before I could win.
