In my personal experiences, it is the other way around. Most people that I know who have suffered their parents badly typically hold their parents precious but without responses from their parents.
I think I read it somewhere, likely a book of psychology or so, that children love their parents more than parents love their children. This statement just responded to my relevant impressions well.
It must be said that evidently my perspective is more of the children, and yours the parents.
I wonder if any netizens in this forum share this view too.
