Douma is an insensitive demon. He enjoys eating women and teasing others. He doesn't seem to consider the feelings of others and seeks his own satisfaction by any means. He doesn't care about harming others. He makes jokes, is manipulative, intimidating, and knows how to laugh at others. He has no feelings and feels that he lets himself be praised as a God. His appearance as a demon didn't change that much because he already he is a bad "person"
