What kind of person would hack his parents?

In most cases, they will not black their parents, but in the following cases, they will mostly black their parents:

The first situation is that young people are not sensible, and they always dislike their parents to take care of themselves, hoping that they know nothing, so they will arbitrarily black their parents.

The second is people who have a particularly bad relationship with their parents. They can't communicate with their parents at all, and even have some irreconcilable contradictions, so they pull their parents out of contact.

The third situation is that parents push their children too hard, so they have no choice but to pull black.
