I thought they wouldn't be straight-up villains, but that's what they're turning into. They're people who have a mania of killing, just like Hollows and most Arrancar. Of the ones we've seem the most, those that seem to be an exception are Haschwalth, Askin Nakk le Vaar,Dr. White-Moustache and the Lloyd brothers (and Uryū of course). Quilge was a very interesting character (his nuttiness reminds me of Szayelaporro), while Driscoll was really dull. BG9 doesn't seem an awesome character, just intriguing. He needs to die, after we've learned what he really is and how he was created.
