It's been clear to me that Diamond Tiara was the most hated character in the whole series before Crusaders of the Lost Mark came along. But since she reformed in that episode, I have wondered if anyone's changed their opinion on her at all. I must admit, I never liked her at first. But in that episode, we found out why she acted like a brat in the first five and a half seasons; because she followed in her mother, Spoiled Rich's footsteps. So, the way I see, Spoiled Rich is the one to blame. I mean, seriously, why would any mother encourage their child to be a brat in public?
Anyway, feel free to vote on the following polls.
