The world doesn't have an odd morality system. His methods were not well received with exception of the mysterious benefactors and their hatchetman. The others have to be corrupted to go along with it.
The game, however, does. You as the player are given opportunities to violate the MC's personal code of ethics by doing things like spying frivolously on the girls, punishing without cause, hiring the dance teacher who has nothing to recommend her, or blackmailing Judith. That's the morality system I'm talking about. And it's one of the better methods as it doesn't have absurd 'good points' but simply different consequences for your choices, good or bad.
