This is messy. I know. Believe me. Heaven and Hell always is.
But you think about your angel choice. Think about what you'd be asking them to take on, think of their weaknesses, flaws, links to humanity if they have them. And please think about helping, even if you don't like the demons, just realise, there are worse, ones that would wipe you all out for the hell of it. Ones that if they got the power of purgetory unchecked they probably could, dooming invincible doombot of doom or not.
Actually would be easier to choose if we had more options that some dude in heaven Cas won't own up to knowing but whatever.

Full disclosure. I had no idea Crowley was planning this. Truth be told, Purgetory terrifies me as a concept. Its the source of power most demons didn't believe existed, and those that did...well, put it this way, even Azazel wasn't willing to risk it.
But maybe, given the freaking archangel and distinct lack of the archangel of douchey life lessons, maybe its the only shot we have.
Also. I'm taking Katherine Pierce hunting a shifter. She deserves a shot same as I got. Even if she is a leech dating a superleech
