[On his post on preventing atheism and claiming that all rejection of the Torah is due to emotional pain which causes people to sin which according to them they then rationalize by denying the Torah]:

If the child has already reached the point of medicating his pain with sex, this is a crisis situation however all is not yet lost. Counseling and therapy, perhaps for the entire family, may be helpful. Perhaps the child can still be convinced to find more positive coping mechanisms. Obviously, a parent must be aware of a problem. Internet monitoring software may be very helpful. If a boy remains in bed until late in the morning this may be a sign that he is masturbating until late at night. A hidden camera with night vision in his bedroom might be helpful.

Once the child has reached the stage of rationalization, and has denied the Torah, then all hope is presumably lost. The child should be expelled from the home in order to avoid a bad influence on others. If he is under 18, then the parents are legally obligated to support him however they should do so by placing him in a boarding school. He should not be allowed contact with siblings.
