If your child blames you for poorly parenting him, you should empathize with him as much as you can. But you also have to evaluate what he is saying. On one hand, you sincerely made your best effort to parent your child in the best way that you knew how. On the other hand, you apparently did cause some lasting emotional harm to your child. How can you evaluate your contribution to this situation? Are you innocent or guilty, or both? The Torah provides guidance on how a person who killed another by accident should be dealt with. The case of the sincere parent is similar and analogous to the case of the accidental killer. This episode examines the analogy in detail and describes actions, derived from this analogy, that the parent can take to rectify the situation to the degree possible.
