"You ever think about those we lost, Dean? And I don't mean just our parents, but Bobby, Ellen, Jo, Ash, Pamela..."
Sam's voice broke, he couldn't continue. The list was never-ending.

Dean glanced over, wondering what had prompted this.

"They all died because of us. We brought disaster on those good people. We're worse than the Black Plague, Dean. And it never stops!" Sam declared.

"Whatcha want me to say, Sammy. Ultimately it wasn't us who pulled the trigger.
Anyway, I'm never gonna be sorry that it's you beside me and not one of them."
