I think many times as a child we can't understand parents love even if they punish us which creats evil thoughts in our mind. I think parents should understand it also and comfort kids after the punishment and make them understand why the punishment was given. Unfortunately, most of the parents do that. It creates the difference between parents and child and it can't be considered a healthy relationship in my eyes.
Yeah, a parent may mean well, but the child needs to at least understand what they are being corrected for and why.
