Even though I agree that punishment is sometimes necessary to teach a lesson to a child, I still think there should be boundaries applied to what kind of punishment is allowed for parents or teachers. For example, people should not use violence as a form of punishment for their children. Unfortunately, this seems to be a normal case where parents or teachers use some violent way as a punishment without considering that this type of punishment undoubtedly will affect the child's mental health. In my opinion, it will also teach children that it is okay to use violence as long as you think that it is right.
