The lifestyle of crime, is ultimatly a self-destructive one and that is what FFC, I think, is trying to get across.

No matter how ruthless or powerful you are, it will still tear you apart and your family apart in some way. In the best case, you will have to live with the fact and the guilt that your kids are in the same racket that almost got you killed and you will be regretful about not having going legit or having the ability to go legit years before (Vito).
