I don't think Sam will be truly evil. He definitely has a dark side and a thirst for revenge. That's part of what makes him an interesting character though!

Yeah i don´t think he could be evil too.

He does have an evil side as a result of the demon blood (his own). He was able to keep it under control for a while, but it was inevitable that that part of him would grow stronger. He definitely has the capability to go evil, and he might take it to the limit, but in the end, I believe his humanity will eventually win out. :))

I think Sam, like all of us, has a dark side. But he is strong and will be able to keep it under control.

I agree with FaithLehane. It makes him more interesting and the show as well.

I agree with fallen angel everbody has a del side but because of the demon blood he has to try harder to keep it under control , poor sammy :(

i know it is soooo sad

Yeah, he's got a dark side, but I think (I hope!!!) he can fight his way past that and be more human.

Yes, and I love it, SEXY
