You think someone automatically becomes predisposed to murder when they join the mafia?

He had it in him, some guys don't.

You only have to look through his history to see the man had an aversion to 9-5 work, a tendency towards violence and would have lived a life of criminality whether he was in the mob or not.

It's certainly not far fetched.

I never said serial killer BTW, but he was directly involved in several and God knows how many more in truth.

Call it what you want.

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
