I know it's a little bit of a childish post on my part but I just wanted to see what everyone had to say.
Vito Genovese wasn't really a great boss. He was a lunatic, and didn't last that long. He had made so many enemies Costello and Luciano set him up and off he went to prison. To be a great boss you have to be liked. That's why guys like Galante got whacked.
