Cain, also known as The Father of Murder, was the first born of Adam and Eve, the brother of Abel, and founder, the former leader, and trainer of Knights of Hell. Cain and his brother are also the direct ancestors to Sam and Dean. Cain became known as the worst demon to ever exist before retiring for love. After coming out of a 150-year retirement to fight Abaddon's forces, Cain fell back under the influence of the Mark of Cain and began slaughtering his descendants, leading to Dean killing him.
