There is a proverb from ancient Greece - Know thyself. The complexity of human nature is far beyond our imagination. The basic binary structure I think is good and evil. Good and evil were divided into two clans. It is a metaphor for the division of human nature. When human nature is divided, are humans still humans? What will happen to the world? How do two divided parts find their other half.
Thousands of years of running away are just a short distance away.
