Not quite sure if this is just griefing or gamethrowing. Ulquiorra is a mason and doesn't confirm his fellow mason Direwolf when he gets put up to trial. Then at the end of the game he suicides causing town to lose.
Also in this game is another game thrower Sponge (1-S2-1-2860102), an arson turned cult, who gave the name of the cultist who converted him.
