[Hermann the Cherusker]

That's why the life-of-the-mother case is the only legitimate exception, because you're trading life for life.

What is legitimate about that?

This case is simply refusing to handle the risks that come with living as a woman by commiting murder. If a woman cannot handle the thought that she might run some infinitessimally small risk of dying by becoming pregnant, let her remain chaste.

Life is dangerous. Some things more than others. Avoiding danger does not justify murder.

[Aquinasfan]

What is legitimate about that?

I'm thinking of cases like ectopic pregnancies, where removing the fetus to save the live of the mother kills the fetus. It's the principle of double-effect.
