The Angelic Killer and the Demonic Savior

Everyone has been taught that angels are good and demons are bad. But, how do we know if that's true? What defines an angel and a demon?

Gabriel strikes awe into everyone that sees him. He is beautiful and the only thing missing was his wings. But his angelic features blinds the truth about him.

Lilith scares everyone around her. Her eyes show death and destruction toward everyone she meets. She is terrifying and the only thing missing was her horns. But her demonic look keeps everyone from seeing who she can be.
