Can forgiveness for the crimes done to a child be not just ineffective but actively harmful? It certainly can because the body does not understand moral precepts. It fights to make our conscious minds admit the truth and transcend our denial of genuine feelings. This is something children cannot afford to do. They have to deceive themselves and turn a blind eye to their parents' crimes in order to survive. Adults no longer need to repress their feelings. But if they do, the price they pay is high. Either they ruin their own health or they make others foot the bill.
