I think Castiel did redeem himself. I mean, we say this all the time, but the road to Hell is paved with good intentions… and he really was trying to do the right thing. If that was his downfall, at least he was trying to do the right thing, you know? And he did redeem himself. Obviously there was still a lot of damage caused, with the Leviathans that we still have to try and [deal with]. But we never would have had the chance to see him doing the right thing, see him redeem himself, unless he hadn’t saved us so many times in the past. So it’s like pot calling the kettle black if we get too mad at him. We started the Apocalypse and everything else — we’ve messed up quite a bit and he’s saved our tushes a few times, so now it’s our turn to clean up his mess."

I couldn’t have said it better myself. Jared. You are amazing.
