I read Anthony Mirra was pretty unstable: if you ask him how his mother felt today, one day he told you "okay", and the other day "what the fuck you are poking you nose into this for?!" or something like that.

Rosario Borgia was more than unstable: when he couldn't buy the Akron police, he just told his men to whack them all (and they genuinely tried to).

Vic Amuso and especially Anthony Casso were paranoid and saw rats in everybody.

And in Sicily, under Riina's rule, crazy and unstable people like Pino Greco, Mario Prestifilippo and Filippo Marchese were pretty common, but were eliminated after having been used to the full.

Willie Marfeo to Henry Tameleo:

1) "You people want a loaf of bread and you throw the crumbs back. Well, fuck you. I ain't closing down."

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
