What does "life is evil" mean and how to understand it?

In fact, the beginning of life is about the original people, that is, people in primitive society and natural environment. At that time, survival came first. In order to survive, people will kill, plunder and be selfish by any means. In such an environment, human nature can't be embodied, and there is only a pure motive for survival, so now it seems that "evil" things are normal in that environment.

On the other hand, people are suspicious and distrustful of each other at the beginning, and they will act in the most selfish way, and everything they do will show signs of "evil". It is the acquired "goodness" that removes the influence of evil.

Extended reading: the theory of evil nature

One of the important theories of China's ancient theory of human nature holds that human nature has evil moral value, which was advocated by Xunzi at the end of the Warring States Period. The theory of evil human nature emphasizes the necessity of moral education, while the theory of good human nature emphasizes the consciousness of moral cultivation. Their opposites complement each other, which has a great influence on the theory of human nature in later generations.
