Who do you think is the worst mobster? Salvatore Riina is the man who single-handedly ruined the Sicilian Mafia. His greed and appetite for power unleashed a wave of murder organized crime would ever see the likes in any where throughout the world. His wave of murder ruined the already tarnished legacy of the land called Sicily. He is currently rotting in his jail cell in Palermo. The man ruined the Sicilian Mafia, which was once for protection, since the pezzonovante of the state did not protect. But after he became a man on the Sicilian commision in Cuppola he murdered more than any mobster ever. He is worse than Gotti. Hopefully that bastard dies soon.
