Well, I'm sticking to "the best" path when discussing that, because usually it's the way a game intended.
It gets really ridiculous sometimes btw, take Eliette path for example. No matter how horrible you will act, no matter how pervy you will be, the only thing you'll loose is a few affection scenes. Imagine if there was an option to turn everyone away from yourself or even get banished from a Keisiema castle for your behaviour. Just how cool it would be to have the ability to mess up that much.
