This view was extremely extreme. Although humans have evil manifestations such as selfishness, greed, deception, arrogance, jealousy, and violence, humans also have many positive qualities such as kindness, courage, wisdom, compassion, and creativity. From the perspective of history and social development, mankind was constantly improving. We have established moral codes and laws to restrain evil behavior, and at the same time, we have raised people's morals and qualities through education. In terms of technological development, cultural heritage, artistic creation, and many other aspects, mankind had made great achievements. These achievements were of positive significance to mankind itself and the entire ecosystem of the earth. Moreover, the extinction of mankind is an unrealistic and unethical idea. We should strive to improve human society, promote positive energy, and actively overcome the evil part of human nature, rather than going to extreme destruction.
Joy of Life's extinction in the previous era was due to humans throwing nuclear bombs at each other, causing the earth to fall into destruction. The nuclear bomb caused a devastating explosion, causing the Earth's atmosphere to be filled with nuclear radiation. This catastrophe caused human civilization to regress to the primitive era.
