Angels have white, feathery wings that constantly radiate with holy energy and purity, they live in heaven. Demons have black, scaly, and rough wings that shine with their sin and hidden intention, they live in hell. Angels care for the human race. Demons hate the human race, they detest the creatures, viewing them as the children of God and deserve to be eradicated. There are indeed gods in the world, they just don't intervene with the bad blood between heaven and hell, a waste of their time.
