God, I hope so! I'm still looking for my jaw after the finale... just wow! The only good thing about this all is that Cas is still alive, but damn! That was just so unexpected, so awesome and I'm not sure that's a good thing :D

i have to hope ! but i am so worried that he is too fargone and past the point of redemption. no no no i can't think like that :(

I think he thinks that he just wants to kill Lucifer and he's a bit carried away by that. But I think that sooner or later he'll be the old Cas-Cas again =3

He has too they are not going to let him be taken over by the power. NO NO NO NO NO

i really think that hes too far gone to be good again unless the writers either drag God in to make Cas good again (which wont happen without Cas being punished brutaly) or they make up a way for sam and dean to purge the evil souls from Cas. In all honesty i kinda think they are gonna have to kill Cas to save him from him self(kinda like the way Jean asked logan to kill her to save the world from dark phoenix). The one thing I do know is that evil Cas isnt going down without a fight.

I believe he'll repair the relationship with Winchester brothers.Maybe he takes sometimes to acknowledge what he had done...And Dean too.I think if Dean forgive Cas in 6.21,where Cas earnestly ask for Dean's forgiveness,he wouldn't turn out to be this way..
