Is rudeus just a bad person

I don't understand why people always talk about his character growth from being a shut in that did nothing with his life and then once he was reincarnated he started doing stuff so that counts for character growth and makes him a good character. none of that matters he still constantly sexually assaults characters that are mentally 38 years younger then him on top of that making him a pedo he also is a bad person constantly thinking stuff like "That’s only because I had no friends besides Sylphie.” Whom I was trying to raise into my perfect, obedient woman." i mean wtf that is insane he is a disgusting person. i love the show and I'm reading through the books but god i cant stand reading shit like this and pretending its okay pls anyone explain to me why rudeus is a good character i want to like him but god its just awful.
