I think he went way, way too far in it.

I never thought so, I never thought that he went too far. He did what he could to keep his family together. Yeah, they had big problems and faced huge obstacles - but together. And that's why I connected with him. This Dean... I don't recognize him and I'm not sure if I even like him. He's turning into John and I hated John. The hunt is everything, no matter the cost to the family. And that's not the Dean that I fell in love with.
