Leonetti would've ended up ratting on Salvie as well. He would've had to kill scarfo and Leonetti. But he didn't know Leonetti was going to rat. Would the crow really not Have ratted if Scarfo was dead? Too many variables. He was involved with a lot of murders. Because of Salvie, that Riccobene civilian relative at the jewelry store blew his brains out. I agree that Scarfo shouldn't have killed him for the reason he did, but he wasn't this docile Mafioso who has a little shy business. He was a killer and involved with drugs.
