If you don't include rape, but you do include incest, why is that?
Finally, how inclusive is the exception of health of the mother? Is it just physical health? If a woman was at an extreme risk of severe mental disorders, or was already mentally ill and pregnancy could aggravate her condition, would abortion be justified? How much of a risk would be acceptable and which is more important: the increase in risk or how much risk there is? In other words, if the mother is 5 times more likely to suffer mental disorders because of her condition, but her risk is still 2%, is an abortion justified?
