Who was the anime/manga character whom you hate like crazy?

Im real mad when it comes to holding grudges for anime/manga characters,the one whom I've hated so much was DAMNED BITCH Kikio from Inuyasha.I detest her no matter what ,I can't ...I just... I really hate her I felt Zero compassion for her (╬￣皿￣)凸 that piece of shit.Huff that felt better.
Anyhow guys I'm curious! Have you hated someone that much to the extent of like wanting to kill them yourself somehow?
