What are some characters who have done terrible shit and had a redemption arc that you can’t forgive

Like Characters who has done deplorable shit and then the author gives them a whole backstory and redemption arc but you still kind of hate them, I don’t hate them that much but I will never like Endeavour, Bakugou, Gabi, Miranjo, Daida, Boji’s father and pink haired girl from magical girl site
