Someone said that mafia kill because it has to be done, but that sounds like - the mobsters are good people, and they are forced to do it, but in reality they are all sociopaths, who care ONLY about themselves and their family, and everybody - Gravano, Leonetti, Caramandi, Jimmy The Weasesl everyone of them claims that killing doesen't bother them.

But all of these people once were kids, some of them even had good parents, so they are not born sociopaths, they became sociopaths.
