I know and i agree with your view of Cas. It's just i'm so used to everyone betraying Dean Cas' betrayal didn't hurt me the way it did to you. I was glad Cas at least admitted he was wrong and didn't blame Dean for that and also Cas feels Dean so to speak. He knows deep inside who Dean is and how much he suffers. I appreciate that about Cas.
Still, no whitewashing, please! No blaming Dean for anything Cas did/does/will do.

I have to say in a long run saving people is not enough cause it runs you dry and you have no will to recuperate. A hero needs his home, some safe place to lick his wounds, and someone to have his back, to rely on. Not in the hunt but in moment of peace.
That's why i was glad Dean had Lisa (before they ruined her). I wish he'd be able to see himself not only as a hunter or a killer.
Right now it doesn't feel like they
re going there :/ But i hope at least in my version of this universe Dean will find someone who finally will open his eyes to show how awesome he is even if not hunting.
