In wall street, the punks worship money. Greed is good in wall street. Bernie Madoff thinks he is a 'good person' just playing along and helping his clients. Bernie Madoff is the 'average hedge fund manager' in Wall street.
Truly evil people have no morals, no soul, and no conscience. Just like Gaddafi, Gaddafi believes his is doing good by killing his own citizens and freeing them from colonism.
Quote from Larson:
The man's conscience must finally be bothering him.
