For the sake of art and culture.
The devil is a lier. Lucifer is the light bearer (attention whore?). Satan opposes goodness.
Would you ever concider yourself a devil, lucifer satan, or view others of having demonic characteristics?
Do you accept the spiritual existence of the devil, lucifer, and satan? Do you welcome them into your life?
Don't have to believe in God to hurt someones feelings or commit a crime. Some people enjoy doing so, that pleasure comes from demons, artistically speaking. Litterally everything is just electrical activity in the brain.
