Theory of Evil Human Nature
According to Buddhism, there is no inherent good or evil in human nature. These qualities are shaped by past karma and habits, like a candle lighting another candle. Mahayana Buddhism believes that everyone has the potential to become a Buddha, which is the basis of all beings' perfection, except for one exception: . Master  of the Tiantai school in the Song Dynasty proposed the idea that "Buddha nature is inherently good and is always good in its expression," implying that there is no inherent evil in Buddha nature.
