10x20 - Angel Heart
It's called the Mark of Cain for a reason! First ... first, you'd kill Crowley. There'd be some strange, mixed feelings on that one, but you'd have your reason. You'd get it done, no remorse.
And then you'd kill the angel, Castiel. Now, that one... that I suspect would hurt something awful.
And then! Then would come the murder you'd never survive, the one that would finally turn you into as much of a savage as it did me. Your brother, Sam.

I MURDER people. bitch'#I also really liked that line#'there is no resisting the mark - there is only remission and relapse'#drove home the point that dean can't become a beekeeper to avoid becoming a serial killer forever#as long as he has the mark of cain he will become a killer eventually#idk seemed like everyone was being overdramatic about the mark's effects before this#in particular bc cain was so unaffected by it in 9.11#so it was like 'it's not THAT bad' ykwim?#but this scene really showed just how fucked up the mark of cain makes people#and the danger it poses
