Why do many people have so much negative energy?

Negative energy refers to always facing everything negatively, holding a negative attitude towards everything, being pessimistic, unable to withstand a little blow, easy to be content with the status quo, unwilling to make progress, and always like to dampen the enthusiasm of others; This is the basic framework of the concept of negative energy. When you measure whether a person has negative energy, you can refer to this standard to sit in the right place. If a person vents his emotions just because he encounters a little trouble, you conclude that this is negative energy, then you are also depriving others of their emotional power in disguise. This judgment is superficial, irresponsible and unfair to others. There are always some happy and unhappy things in life. If you don't let others express themselves through emotions, do you want others to be great saints who are neither sad nor happy? People have emotions, which is the most basic common sense. If you judge others as negative energy when you see them crying, angry or sad, how many negative energy people are there in this world?
