GoodFellas
“Never rat on your friends, and always keep your mouth shut.”
Henry knew these two were the most important rules of the mafia, he followed them, until he realized his so-called “friends” are no longer loyal to him, jimmy was planing on killing him, Paulie, who once was like a father figure, distanced himself and never showed care when Henry wasn’t around.
So I liked how Henry chose himself at the end, his life, maybe as a nobody, but he did the right thing, it was a masterpiece for the saying that says ‘your best friend can be your worst enemy.’
