Magic Knight Rayearth is a show notorious for giving all of its characters a sympathetic, or at least understandable, motive for what they do. Nobody is a Complete Monster here. Except one: the Big Bad of the second season of the anime, Lady Debonair, an Eldritch Abominationborn from the collective fears of Cephiro's people who wants (just like the above-mentioned Wiseman, and possibly Yuki and Johan) to destroy the world for no understandable reason, cannot be reasoned with, and will use any despicable trick in the book to get her way. Even reading this does not convey how horrible she is, but when she abandons her own "daughter", Nova, to her fate after she fails in defeating the Magic Knights...well, that's when it truly sinks what kind of monster we're dealing with.
