No real hate, but in order of dislike, from most disliked to less disliked:
1. Lucien Lachance - arrogant and incompetent
2. Farwil - for general jerkiness
3. Falcar - traitor
4. Mannimarco - for evilness
5. Countess Alessia Caro - for racism
Subject to change. Strangely no Bosmer's on my list. They are annoying but somewhat likable.
I"m interested in why you hate High Chancellor Ocato
