Look he was a mafia boss at a time when treason and murder were all around him with his bosses before him .

He was a stone cold killer and borderline mental but if you look at all the others before him with bodies he looks like a regular guy.

The restaurant murder was self-defense Nick was small the longshoreman was huge there was a knife (what would you do) if you are a made guy or in the life you are killing the guy .

Start counting the bodies of people in NY that were not made that disappeared or chopped up or left to die "thousands" it's the life back then.
