The majority of the major Garlean aligned characters are, for lack of a better word, Madmen.
Valens, Nael, Varis, Zenos, Yotsuyu, Asahi, etc... Sure we get a couple that break the mold in the form of Gaius and Regula, but the majority are walking war crimes. So claiming any type of grey morality, outside of a few situations, is wishful thinking at best. As for Misijia, much like Yotsuyu, her character and crappy "redemption" arc ruined the story for me. It would have been better to let her skull of been ground to paste beneath the WoL's boot in DR>
