aren’t we all sinners?

The serum amplifies everything that is inside, so good becomes great; bad becomes worse. This is why you were chosen. Because a strong man who has known power all his life may lose respect for that power, but a weak man knows the value of strength, and knows compassion. Whatever happens tomorrow, you must promise me one thing. That you will stay who you are, not a perfect soldier, but a good man.

Summary: When you became an Avenger, you thought your past was buried deep enough to never resurface. But when your skills as a hunter of the supernatural are needed, you’re forced to reveal more about your former life.

Characters: Bucky Barnes, Dean Winchester, Steve Rogers, Sam Wilson, Natasha Romanoff, Sam Winchester
