You said it yourself. You weren't you. A lot of people weren't themselves 'cause of what Famine did. If they can't understand the difference between you now and the you that got caught up on account of some messed up outside influence, then they weren't even trying to trust you to begin with.
If they're gonna turn against you because of this, they need to take a good hard look at everyone else too. If you were to come with me, you'd just be supporting me. And it's not so bad. We're just trying to save someone at the cost of a few people, but they were probably already dead anywa.
You don't know how to get someone out of Hell. You said it yourself when Dean was trapped down there and I was begging you for a way to get him out, remember? There's no exit. Not unless there's an angel willing to tough out the pit for you and Dean was the only one who's ever had that happen before. Cas is outta juice and I sincerely doubt that Anna or Gabriel are gonna go diving into Hell for one person.
