Idk, cosa nostra had its share of sick fucks. Roy Demeo eating pizza and pasta while cutting up bodies, or Tommy Pitera decapitating an alive naked girl, and then putting the severed head on the ledge of the tub sound pretty fucked up to me. I also read in a book once about some neighborhood drug dealer in NYC that was given warnings to kick up or something but didn't listen, and then beat him so badly to death that the police thought he had been decapitated because his head was crushed into his chest cavity.
