That makes sense, war equals less money. It seemed like the Scoppas had a problem with Greg Woolley, seeing as they’re from Italy, that would make lots of sense. Putting a black first, instead of their own, would never fly, let alone be possible in Italy. Now, the Scoppas and Picasso are dead wtf!
It's possible they had a problem with Woolley but not because he was black. Judging from Andrew's book, their(or his) problem was mainly with Steve Sauce(Stefano Sollecito), and Woolley was brought in by Steve as the Rizzuto's muscle, and Andrew may have been jealous, Andrew turned on the Rizzutos after Vito died because he felt they didn't appreciate the help he gave them while Vito was still inside, and he thought Steve Sauce was manipulating Vito, clipping people he had a problem while pretending he was "cleaning house" for Vito.
On the other side, Steve Sauce and Woolley thought Sal Scoppa was a snitch and was stealing from them and wanted to clip him, but Leonardo said no. But word was leaked back to Sal and that's when things kicked off between them.
