My dear boy, Crowley and I have been spending time together periodically since our time here on Earth, and in that time, I cannot say I've seen him ever be truly evil. Not even in the Garden, he might wager. Though the ethics of what he did there is not why we're here.

I cannot say he's ever collected a single soul in his entire existence. Gave a little push, perhaps, but not any more than you or I might do for someone to Our side.
