Well, her motives as a villain were ridiculous and senseless, and while I do think her character now is kind, I've always hated how much protagonism she's recieved in the seasons 6 & 7 (I think it was those seasons, I don't remember, it's been a long time since I've watched MLP), it was excesive. It felt like the Mane six were no more the main characters, but that random villain who turned good.
