Why do people lose the ability to doubt human nature? This is related to a person's reading and TV series.
Many people grew up reading the Three Character Classic since childhood. The first sentence: When a person is born, he is good in nature. The nature is similar and his habits are different.
It is inherently good, so people will think that they are kind, gentleman, and have noble morals. Being kind is inherently good makes people start to be proud. I was born kind. I don’t know that the essence of human beings is inseparable from good and evil. Once you distinguish between good and evil, you will basically make mistakes.
As long as people read the Three Character Classic, they form the habit of pride. I was kind, I was right.
This kind of pride makes people overestimate human nature and think it can withstand the temptation of money and beauty.
Everyone is unwilling to admit that they are a villain and always think that they are gentlemen. People cannot understand human nature from reading and lose the ability to doubt human nature.

Another one, from novels and TV series, basically everyone knows that Tang Monk's ability to resist women's temptation was too high. She saw that the queen in the Kingdom of Women had the right to leave, was beautiful, and was willing to marry him, but Tang Monk did not give up going to the West to seek scriptures.
Tang Monk can withstand the temptation of the beautiful king.
The story of Tang Monk tells everyone that a man with noble morality can resist the temptation of a woman. A man will not waver in the face of temptation and will not do anything wrong.
No one reads novels, and after watching the TV series "Journey to the West", they basically believe that people can resist temptation, just like Tang Monk. As long as a person has a firm goal, it is fine.
The real situation is that people cannot resist temptation at all.

People are reading, in TV series, and the people they see in novels are all false, they are overestimating their humanity and overestimating their ability to resist temptation.
These effects will not make people highly wary of their own humanity, and they will also lose the ability to doubt humanity.
In order to avoid doing evil, it is to avoid the temptation of power, beauty, and money. Only by staying away from the temptation of money and beauty can one make fewer mistakes.
Because people are tempted by money and beauty, no one can resist it.
In Western society, everyone is a sinner, and there is no righteous person.
This tradition makes people wary of the evil of human nature and know the evil of human nature.

Since childhood, I have been reading literary works and TV series that beautify human nature and overestimate human nature. In the end, people basically overestimate human nature and imagine themselves very beautifully. Loss the ability to doubt. But forget that when people encounter temptation, they basically make the most wrong choices.
Overestimate human nature, making people very proud, making people overestimate themselves, overestimate their diligence, and overestimate their abilities. This overestimation makes people unable to correct it at all.
Some people just make mistakes until they die, and they will never change.
Knowledge people don’t even have products with property rights, so they think they are very diligent.
A person who truly knows human nature will be humble, and he knows that people do not encounter temptation. The right choice can be made. Once you encounter temptation, make a mistake immediately.
