One of the many sons of god who wanted to rebel because he did not understand that his father did not want to grant men the light of knowledge and preferred to content them with the darkness of ignorance. the ignorance of a balance between good and evil.
that could have made them aware of their actions before the plague that war and perversion was established among humans by scraps, rotten in the soul then God felt mistrust or his son simply asked him for trust. when he was his son he became his opponent and now all the men they had fought for rejected him the fault of all their sin The anger invaded him and transformed while his wings and his soul turned red in hell so he decided one thing

Lucifer promised that they would forgive men, but he vowed to take pleasure in torturing those who commit sins in order to deter others from the path of evil.

You wanted him to be the devil and yet...

feel the unbearable regret you feel at the fact... being that right.
