I agree that each of those you mentioned were far from "pillars of society." That said, there are many, many who are not killers, and have little to do with violence (believe it or not).

The guy who got hit with the golf club was "Jimmy Sinatra" Craparotta. He was not a civilian. And Avellino didn't order those murders. He "asked" permission, but ultimately only the boss or underboss can order that.

Furnari, Sessa, and Gravano, were all a bit twisted. And admittedly there are a lot off guys that are violent. Some depraved. But I dare say that the majority of street guys and racketeers don't have those traits. That is what has actually "ruined" the "game plan" so to speak. Violence, begets violence. And it often escalates.

History has proven that the guys who stuck to running their bookmaking and shy books (and other schemes) and stayed away from violence mostly died in their own beds. Many lived profitable and constructive lives believe it or not. They were largely accepted by their communities and were well liked. And their blood families benefited from their outlook on life. Whats the old adage? Those who live by the sword, die by the sword. That mostly true. Especially in the underworld.

The ones that we typically read about, the violent ones who had little regard for life, mostly ended up dead, in jail for life, or became rats to save their asses.

The smarter, savvier and more level-headed guys, those not prone to violence. They fared much better. Even law enforcement recognized that difference.
