Parents want their children to grow up healthily and happily, so many people will try their best to keep their children away from negative information and prevent them from realizing the cruelty of society. However, whether children should know the cruel facts of society is a question that needs to be discussed.

First of all, we need to realize that the cruel reality of society is inevitable. When children grow up and start to face these problems, it will be even more unbearable if they are not prepared. Therefore, it is beneficial for children to realize the cruelty of society from an early age for their future growth and life.

Secondly, making children aware of the cruelty of society is also a protection mechanism. If children know nothing about the real situation of society, they can easily become victims. For example, children may be abducted by strangers and suffer physical or psychological harm. But if children are aware of these dangers, they will be more alert and cautious, will not trust strangers easily, and will be more able to protect themselves.

Finally, letting children know the cruel reality of society is also to let children better understand their own situation and social responsibility. In this society, everyone has his own role and responsibility. Only by knowing the real situation of society can children better adapt to and understand the world. They can also better understand how they should do it and how to influence the world.

Of course, this does not mean that we should tell our children all the cruelty and injustice. Parents need to judge according to their children's age and maturity and adopt appropriate methods. Children can gradually realize the complexity and cruelty of society through heuristic education, stories, books and movies. In this process, parents need to communicate with their children, guide them to see the world correctly, and cultivate their independent thinking ability and judgment.
