Robbie Baldwin only became Penance after being directly involved in the demises of over 600 innocent people. Graymalkin was buried alive by his father because he was gay. Jessica Cruz spent years locked in her apartment struggling with guilt and anxiety after a bunch of mobsters killed her friends in the woods.
