Lansky: Yes. The Bug and Meyer mob was violent. I can also see him whacking a Nazi supporter in NYC during WWII.

Gambino: No. He was born into a mafia family and was well connected in NYC before arriving. I don't think he ever pulled the trigger, mostly because he didn't have to.

Bonanno: Yes. He was Maranzano's underboss and chief of staff during the Castellammarese war. He was in his twenties and probably fearless back then. Plus, he supposedly owned a funeral parlor that used double decker caskets, it makes it easier to believe that he was hands on with the murders.

You shit-kicking, stinky, horse-manure-smelling motherfucker you! If you ever get out of line over there again, I'll smash your fucking head so hard you won't be able to get that cowboy hat on. You hear me? Fucking hick. -Nicky (Casino)
