Who have you hurt Castiel, under orders from what we now know to be wrong. How many? Your vessel, did he truly understand what you were asking of him? Crowley has done a lot to change since being here, he hasn't made deals, he hasn't unleashed the rather considerable power he could have. I don't expect sainthood, I can't. He is what he is, but he's trying. Kol too, and they're not doing that just for me.
No, of course not, because you've happened to fall for two humans. Me, it wasn't so easy. But under the law you've committed a grave sin too, haven't you? That is why this IS about our father, unless you believe he created us wrong. Lucifer believed us to be without flaw and humans to be the abominations, its why he twisted their souls after all.
