And certainly no one can argue that killing a diseased or disordered fetus is therapeutic to that fetus (such an argument considers the fetus to be a patient that is receiving therapy, but intentionally killing a patient is never therapeutic). An extremely small percentage of abortions are medically necessary to preserve the woman's life.  As to preserving the woman's health, destroying a healthy pregnancy by inducing abortion does not preserve a woman's health. Rather it destroys and undermines her healthy reproductive system. It may be what she wants, but it is not therapy. Much like amputation is not therapy for the person who has a psychological need to have his healthy hand amputated.
