I have seen parents act violently when their kids are scolded and it just pisses me off a lot. They watch and pamper these kids until they become a problem in society.
Although, parents aren't the only ones responsible for a child upbringing, they have 99% of the task because in the end, whatever the child becomes is theirs.
As in ehn... they're the ones who will suffer it the most, so it makes no sense that they keep enabling them.
