The initial impulse of nature is always right, there is no original sin in the human heart, and the evil within can find its source from outside.The only natural emotion is self-love, which is often called selfishness.This selfishness is good in its nature, and is of great benefit to us, and nature is just to them.This kind of self-love, for better or for worse, depends entirely on how one uses it, or what kind of relationship is established in the way of self-love.
