Regarding killing everyone, the last two bosses were killed. I'm sure there was some paranoia that played a part. The Ricobene thing was a little too much. I always wondered why Manna or N.Y.for that matter didn't intervene and make Scarfo calm the fuck down. A white rolls Royce and boat named the usual suspects probably didn't help with law enforcement attention either. Phil and Salvie should have killed Scarfo and brought peace to the family.
