One thing I know for sure, infighting and killing for the top spot is the dumbest move a Family or organized crime group could ever make. Look at what happened to the Colombos, 30 years after the last conflict ended they still haven't recovered. Infighting practically wiped the Rochester Mafia out of existence, and fighting Danny Greene is the main reason the Cleveland Mafia is almost if not fully nonexistent today. Even the Bonanno Family, when they avoided a war by smoothly taking out the 3 rebellious captains. Sure, they got away with it for a long time, but it came back to bite them in the ass 20 years later. Imagine if the early-2000s indictments came down on the Bonannos without those 3 murders looming over their heads? They'd be in a little bit better shape today I think. Also, they could've avoided the Gerlando Sciascia murder. Also, bosses killing for little to no reason at all, like Vittorio Amuso/Anthony Casso of the Lucchese Family and Nicodemo Scarfo of the Philadelphia Mafia, those 2 Families also haven't been the same since. The Stanfa/Merlino war also didn't do the Philly mob any favors.
