Times when the character in a story learns the exact wrong lesson?

So a big part of the witcher series is that Geralt’s “all bad things are bad I would simply not choose if there was a lesser and greater evil” ideology is terrible and thus he often does pick sides because deep down he does want to be a hero and do the right thing, so I wanna shoutout the short story in the first book that introduced it to us.

Geralt pulls his “I’m not gonna get involved all sides terrible here” shit in a conflict between a wizard and a princess, and then he does get involved anyway because he learns that the princess is going to commit mass murder and decides killing her and her buddies is a lesser evil he can go with. After he’s done butchering most of the assholes she shows up and tells him “oh ya actually I’m not gonna do mass murder at all because it would be pointless” thus hammering home the idea that he should’ve just not gotten involved because then no one would’ve died.
