Dean to be blamed oder not?

first i'm a dean Fan and also a castiel fan...
this season, the brothers were not great with castiel,treating him like a dog...they always called him for asking help and never just to say hello how are you?
dean saw that something worried with cass but not really asked what's wrong...sure he asked him what's the matter , would Du want help...but just asked the Frage and never want to really have the answer...it was not a friend reaction...he forget quick all that cass're doing for us...yes he tried (but no really hard) to take his side against sam and bobby on the 6.20 but quick turning against him...when Du saw how he treated castiel in the 6.19..that's pissed me off..i always sagte that castiel Liebe the bro Mehr that they Liebe him...he Lost everything for the bro and always be there for them...but them? now what they'll doing about the castiel case?...help him oder try to kill him?...all happened in the (average) season because castiel didn't want to disturb dean in his new life with lisa and ben...again for their good..and him, who was there for him...nobody except crowley...no brothers, no God, no nothing...
so yes, i understand a part of the reaction of your friend...really i have this impression this Jahr that castiel was totally alone and so desesperated that he made the worst choice of all to win his war beginning because one day, this awesome Angel – Jäger der Finsternis took the side of 2 brothers against HIS boss...
so yes dean was not a great friend this Jahr and i hope that Weiter Jahr he will be the best friend of all...because i Liebe him and want to see him fighting for this friend that he called "brother"
sorry for being so long...but i Liebe castiel and Liebe dean and disliked this season...

i will not talk about what happened cause we all know . so i am gonna make this short .
No matter how much CRAP u pull and i mean every one ( in the Zeigen of course) that doesn't give the right for cass to torture that poor women just cause she is a monster doesn't mean she doesn't feel!!
i was on cass's side all along but about 3 days Vor watching s06 knowing cass is working with crowly ( cause of cass sam and dean were working with crowly check it!) and i know i know how badly the boys treated cass ( badly is understatement) but that doesn't give him the right to be the new god!!! and ask every one to bow for him!!!!
HE killed Balthazar ( which i really liked) cause he helped the boys . Your closest brother helps sam and dean and what do u do KILL HIM!!!
.i am really sorry i am emptying my rage here. but honestly Cass dropped the ball BIG TIME , and what he did to sam !!. Dean is NOT an excuse for what cass did , sam n dean they have their issues but they don't open purgatory !

i am disappointed and really angry at cass in so much way that the boys didnt even measured to.

let me just say...im a huge dean fan. and he is not to blame it was castiels choice and he could go either way the winchesters had nothing to do with it and dean is like castiels best friend

NOT NOT NOT.

Castiel made his OWN choices. No one could have stopped him. That much was clear .. and the people who tried ended up dead. (Rachel, Balthazar)

I don't blame either Dean oder Sam for what Cas did he did this to himself & in my book now he's no better then Lucifer... We also need to remember Sam called for Cas and he ignored him after he was freed from hell and spying on your Friends that would help Du in any situation without asking for help Du turn to a demon instead...Along with Cas throwing a fit once Dean got Sam's soul back made me Frage if the fit was because he cared oder because he wanted Sam's soul all for himself..... If he can't be saved they need to kill him off.

even if dean would have helped cas still having all those souls in him made him feel powerful and develop a massive ego so nothing would be any better he would still think he's god and plus he sagte he would kill them if they diddn't kneel down to him he's a bad bad god

I am a dean Fan but I do think Dean couldve handdeled the situation better. He shouldve listen to Cass each time he went to him instead of just telling him to take a hike. then maybe he couldve helped cass come up with a dif way.
