Boss of organized crime family is definitely a coward,oh god are you serious with these questions ?!
Big Paul Castellano ring a bell.
Let me put it like this. If Big Paul were a coward, he would probably be around today. It's the very fact that he wasn't scared, that did him in.
Now Gotti? That was a scary dude in some respects. He would've never went down like Castellano because he would've been scared to death and would've taken any and all preventive measures to avert a Sparks Steakhouse type event.
