Most mob bosses are narcissistic and sociopaths. I love sammy’s channel but he is a sociopath. They justify the murders and convince themselves it was the right thing to do. Mob guys can be very smart and cunning opposed to a gangbanger for example. Thats why mob guys are dangerous.
Gotti was in some ways created by the media. Also getting tens of thousands of fan mail while in jail certainly didnt hurt his ego. Certain people, and gotti was one of them, are born leaders, its an Xfactor that only certain people have. You dont become boss of the largest crime family in America and boss of a bunch of killers for being stupid.
Getting back to Sammy, i firmly believe he concoted stories about certain guys becoming a threat just to take their money. Gotti wasnt like that.
