We are wasting time they need us to spend on the fight.
Of course you'd think that. Sam and Dean? They have faith in me. Took me a while to see it but They'd made mistakes before, maybe they are making one with me, but I know what they would want me to do. I know what's right. If I was going to take out the werewolves and the vampires they'd already be gone yet I have made no move. This vendetta I have against them is merely your fiction.
Yes. It's easier for you if they see you as a hero.
