Vito was a heavyweight no question. But he had to wait for Willie and Albert to be out of the way before he made his move on Frank. We all know Frank wasn't a killer and didn't like guns, so Vito knew he could push him over real easy. Joe had the political influence like Frank Costello. But unlike Frank he used to be an enforcer for Frankie Yale, his name has been mentioned with several killings, and he knew how to make money legally and illegally. So if Joe had become boss, knocking him off wouldn't have been easy.
Genovese was behind all of those hits. Everyone knew it but did nothing about it.
Adonis was a killer in the 1920's. By the 1950' he was living the high life for 30 years. Genovese was still a street guy
