What does the story of the farmer and the snake illustrate?

The story of the farmer and the snake tells us that as a human being, we must distinguish between good and evil, and we can only extend a helping hand to kind people, and we must not be merciful to evil people. Story:

A farmer encountered a snake in winter. He suspected that it was stiff, so he picked it up and warmed it with his own body. The snake was frightened, but Naisu used his instinct to bite the farmer with his sharp teeth and actually killed him. On the verge of death, the farmer regretted and said: "I wanted to do good, but because of my shallow knowledge, I actually harmed my own life, and I suffered this evil retribution."

On a cold winter day, a farmer returned home from the market. I found a snake on the roadside and thought it was frozen, so I put it in my arms. The snake was frightened, and when it fully woke up, it instinctively bit the farmer and finally killed him. Before he died, the farmer regretted and said: "I wanted to do good things, but because of my shallow knowledge, I killed myself, so I suffered this kind of retribution." Meaning:

This story is about being a human being. We must distinguish between good and evil, and we can only extend a helping hand to kind people. No matter how kind and righteous you are to those evil people, their nature will not change.

Don’t trust others without knowing their identity or whether they are sincere in their hearts. Bad people will not be moved by your enthusiasm. We should be careful, but don't begrudge helping good people.

Short: This story warns people not to be merciful to evil people. New ideas:

Kindness, bravery, trust, selflessness

Kind people are often not understood by others. This principle also applies to today's society. To the nature of snakes. In winter, whether on the roadside or in caves, due to the drop in temperature, they can only choose to hibernate for a period of time to survive. The farmer didn't know this truth, so the snake bit the farmer. Let's not first discuss whether the snake was poisonous or non-venomous. One thing is clear. The farmers themselves are half responsible! This story has led many people to misinterpret what snakes really are. In fact, the current saying is that goodwill is not fraternity, and understanding is the king. If the farmer puts the snake into the tree hole, I think this fable will have another meaning.
