Lucifer is a clown.

If you look at a clown and expect purity, wholesomeness, and innocence, you are a fool. It is the nature of the clown to be wicked, demonic, and have no sympathy for the human race or any of their struggles. They laugh as humans worry about war, money, heartbreak, and disease. All they do is ride a unicycle, juggle, and create balloon animals while the human society bursts apart at the seams. They are untouched and do not care. They find humor in the struggles and the tears.
