I agree. I'm glad I'm not a Samgirl because I'd feel obligated to defend or make excuses for this behavior. But you know, regarding "he's not Sam at all anymore"...I kind of feel like Sam always had this side to him. If Jess hadn't been killed and the Yellow-Eyed Demon hadn't come back into the Winchesters' lives, do you think Sam and Dean would have been close? Do you think there would have even been any place for Dean in Sam's life? I doubt it.
