As a Dual Personality, I

The world says that killers are ruthless, but they don't know that killers also have their own difficulties. When people live in the world, there are only three consequences of human heart: becoming a devil, becoming a saint, or becoming an ordinary person. The rules are set by man, why should I abide by this unchanging law! ? I want to treat a mortal man and do evil things as a sacred heart!
