Human nature is ugly because it is full of desires. Human nature is also great because it is full of endless hope. Since the development of human society, it has always been the law of the jungle where the jungle prevails. The so-called righteous ones make their own rules to protect the weak, while the so-called villains act recklessly and crush the weak like ants. But, does so-called justice really exist in the world? The answer is actually vague. This is as incredible as the Buddha saying that you can become a Buddha immediately by putting down the butcher's knife.
