Suppose you're a Catholic doctor, who has the training and skills to perform a safe and medically-qualified abortion. Now suppose the life of your pregnant Catholic wife is seriously endangered and she will die if this pregnancy is not terminated. You know this to be a medical fact, beyond doubt. The baby is one you both want.

You commune with your conscience, your wife communes with hers, and you both come to the conclusion that you must perform the abortion to save your wife's life. It is really "trading" a life rather than taking one, because the wife will die if the baby is allowed to come to term. The alternative is that the baby dies and the wife lives. But that's assuming a normal healthy birth. There's no guarantee that the baby won't die too, at some stage, whereas the wife *will* without this intervention.

Using Joe's reasoning, in this case it would be OK for the doctor-husband to perform the termination, because they have sincerely consulted their consciences. Is this correct?
