You Should Fear the Devil

He was killed because he was involved in other people's "family affairs", but he never thought that he was actually the king of demons. If it is just pure killing, it is too simple for powerful demons - they should be made to feel fear, they should be made to surrender, and the power and terror of demons should be spread to any corner of the world, and even to any corner of another world!
