Big Paul was a lot of things but im not sure I would say a coward. Greedy? Yes Not a street guy? Absolutely. However I could name a few instances where he kept his mouth shut and didn't sell anybody out. When he was 19 he robbed a store with some friends and he was the only one who got caught. Instead of ratting he said nothing and went to jail for a little bit. The other time was the apalachin meeting where he was one of the mobsters detained and didn't say anything either. IM not trying to praise Castellano but I don't consider him a coward really
