"Then imagine hundreds of years, thousands, more. Of watching them fail and fall and knowing nothing you will do will ever actually help them. Watch them slaughter each other, main each other, hear their voices cry out for you again and again. Watch and see the few who are truly wicked destroy so many of those who are good, see those who are good become evil because they just don't know what else to do - and then Castiel, look at all of them and tell me that you think that is what God wants for them." Raphael didn't. He simply could reconcile something created with such importance that it was worth what God had ordered done to Lucifer, worth the pain it was causing Michael, worth them who had grown and lived at His feet, with the neglect he saw in their care. Couldn't look kindly on something that had so much promise waste so much of it. He was disappointed in humanity, and felt that they, like the Host, had been abandoned by their Creator. And he didn't know what else to do for them.
