Yes, Indeed. They are called demons by mortals...
Creatures who were rejected by God for being too corrupt.
Once angels who were on God's side, but now cast out of paradise and abandoned in the confines of a world in decay.
Punished by the creator himself to be the representation of all the 'evil' of humanity.
Creatures that when mortals think of the word 'evil', the word 'demon' certainly comes to their minds.
Condemned to roam the seven hells for all eternity, demons are the result of a single action...
'Sin'.
When people kill in anger.
When people envy other people's goods, and steal those goods.
When people are too lazy to do something.
When people are very proud and believe they are always right, consequently harming another being.
When people have an insatiable gluttony and do not share with their peers despite having better conditions.
When people accumulate enough goods without need.
