They do not want to scare their already intimidated parents even more. And not only that. They cannot take parental pressure any more, and beatings would only contribute to that pressure. We have been humiliated, minced and intimidated as people. We have become morally degraded.

If they could, they would lock up their children in drawers. And the youth simply won't accept that. She does not justify their behavior. She fears for the future of her own and other people's children. If students, with assistance of their parents and others do not succeed to secure for themselves even a minimum of moral rights, they will end up as a failed generation.
