Um.
Just how exactly are the Quincy's more depraved and malevolent than AIZEN ever was!?
Aren't they simply exacting vengeance for the Quincy massacre? I'm not saying revenge is benevolent, just pointing out that it's quite not on the level of "creating life, killing the king, and taking the throne of God."

This is a real question, maybe I'm missing something. Or something has yet to be revealed about the Quincys.
