Alot of these guys have these HUGE CHIPS on their shoulder's especially from back in the day.
You see they were treated like Royalty in the neighborhoods they came from and it went to their heads.

Its not like that anymore today for the most part.

Alot were STONE COLD and you could see it in their eyes

From personal experience two of the nicest wiseguys I met were Mikey Scars and Lil Robert Lino, they both conducted themselves as gentleman they were both captains when I met them so had power within their families.
