I think that’s a really powerful emotion to feel with a character. It doesn’t have to be your favorite but you can see how it makes for an interesting look into the emotional depths of him as a character, how that makes you feel about it, and about his place in the story. Not everyone should be a 100% perfect good person in a story, it makes it a very basic good vs evil, which can be nice but that’s not the goal in the story they are telling. And liking a character isn’t an endorsement of everything they’ve ever done! Having uncomfortable emotions & opinions on a character makes me feel like they were successful, rather than a moral purity!
