Becos gaspipe was on his ass, Casso hated big Paulie and kept calling Johnny talking about how big Paulie was gonna whack him. He didn't tell Johnny that Paulie was greedy, Casso told him that Paulie was gonna whack him "Do or die"! Then when Johnny whacked big Paulie, Casso said "would you look at dat, they whacked the boss". Casso then puts Lil Al in charge to take care of Johnny. You couldn't trust anybody. The only thing that could be done at that time was to keep an eye on everybody. How do you do that by bringing them together find out what they're up to.
