I am just a fan and make no profit from this.
Of course Sam would save Dean if it was within his power. BUT Sam said "The same circumstances" meaning he wouldn't take Dean's choice away/trick him, like what Dean did to Sam. Sam's been tricked/manipulated by Lucifer, angel's, Ruby, being fed demon blood etc and he's upset cause Dean lied to him and won't say sorry.
Agree with every word but I understand Dean too. He was saving his brother, it's only family he has.
On this line--BULLSHIT!!!! Season 3, anyone?! Sam was willing to do ANYTHING to save Dean!
Someone get Kripke back as a writer before I go postal on the other writers!! The past couple seasons have been 31 flavors of WTF!
When Sam said this, it spoke of anger and resentment for him. And this doesn't mean that he wouldn't save his brother at all. Just in the same circumstances... he would try to come up with something else, or would just talked openly asking Dean accept an angel.
