Let me talk about the benefits of bad people. Have you ever thought about the contribution of bad people when you criticize them? If everyone is a good person, then the world will have a qualitative change. The premise is wrong. Good guys and bad guys don't exist simply. Everyone is a combination of angel and devil. So, your conclusion is wrong. There is no need to say that there are bad people to promote social progress, because everyone may have good deeds and bad deeds. There will be no complete "good guys" and no complete "bad guys" in the world. The fundamental driving force to promote social progress comes from human wisdom and creation, as well as human understanding and management.
