A pause would be good.
"get some rest"
There's a bit of a "lay down your burdens" theme at the end of S2... Dean talking about being tired of hunting, extending through to him giving up the hunter's life permanently by giving up his whole life. I think there's more at work in this, but that's definitely a theme you could see.
hates his father's f***ing guts
I don't know that that's true. I mean, sure, maybe a little resentful that they have to give up everything to fight, that they're the ones who have to make the sacrifices to save others. But I also think Dean really believes in what he does, in the importance of saving people, not just out of familial obligations. After all, it was the impetus of all those other deaths that drove him out of the wish at all...
