Seifer was definitely a douche, but that's why I liked his character...? xD I really liked the 'I hate your guts but I weirdly respect you, making me not actually hate you' relationship he has with Squall and the arguments he and Zell got into. "Chicken wuss" xD

(Spoiler) I also like the fact that after being one of the main villains through half the game, in the end he's just fishing and chilling with his 'posse' and getting mad about not catching any fish.
