According to our religion, everyone will be held accountable for their actions. The other is not responsible for the sins and rewards of one. If a parent commits a sin, he will be held accountable.
A child can be held responsible only if he shares in the parent's sin and does not prevent him from doing wrong. It is not the child's fault that some children are born disabled due to parental fault, and it is wrong to accept this as punishment. After committing certain sins, a person must wait for the consequences according to the laws of nature.
For example, a person who falls from a height must be prepared to be injured or even killed. This is not his fault and is not a punishment. It is a natural law for parents to make some mistakes when putting the baby's sperm or during pregnancy, the result of which will affect the child's health.
