Although killing will certainly bring a lot of heat, cosa nostras only way to rule is by fear. If you lose the ability of killing, sooner or later people will not afraid of you and partners will betray you.
I disagree. The first rule of the mob is make money. It is not necessary to be a killing machine.
But make money means keep your head under the radar (In intact states). So if you use violence it has to pay off. For example a debtor walks around talks to everybody he don't buy back. They mob will break him his legs or kill him.
But a guy they snitch twenty years ago. Nobody knows it is true or not also most involved guys are death or in jail. Why a captain should risk his racket ? He can't win anything.
They legit business partner will have trouble. Maybe you have a soldier with a murder case. That's the next risk. Maybe you need kill again. Now you have two murder cases.
LCN and CN in Sicily lost a lot of power with senseless violence.
Another point a lot rats are back in criminal business so maybe someone get money to protect her rackets.
