Some people say that where there is sun, there is light everywhere. Anyone who has experienced life knows that the most important thing in life is not to hurt others, but to have enough means to avoid being hurt. For example, I have met similar people before.

An obvious feature of people with dark hearts is that their hearts are higher than the sky. They are very good at taking advantage of human weaknesses, such as pretending to be poor and weak, but once the time is ripe, they can definitely refresh your three views.
