Education

Now in Japan, -I have no date any other country-, "Child abuse" is one of the most important social problem. The parent hit or kick, its a violence, and kill or injure their child. They excuse "I'm apology for my son or daughter but it was discipline." for those violence, after their child dead or injured.
Discipline? What is it?
Do they have a requirement to daughter?
Why we can say adult is right and child is wrong?
Education is, namely, press adult idea on child.
