Why should the child be punished for the crime of the parents?

Hello everyone,
Greetings to all of you, today's topic is very interesting. Today I am going to talk about a deranged society where the parents' crimes or their mistakes are punished by the children. Where the children are victims of the sins committed by the parents. Although they don't know how much crime his parents have committed or about his parents' crime. Even though they are not born into the world then many people think that the child should be punished for the actions of the parents. I think this is a phenomenon that people will understand if they consider it. Because these children don't want to remember past sins. In fact, the people of this world are very cruel.
