Jill has a tremendous post about how abortion is in fact a moral good. Once you think it through, it’s fairly easy. Abortion is a beneficial medical procedure that removes something that is often a health risk; childbirth is as a rule more dangerous than safe abortion. As Jill notes,
Some on the Pandagon thread argue that procedures like heart surgery are morally neutral. I don’t think so. Having access to that surgery in the first place is a moral good. Deciding to take the course of action that is best for you is a moral good. That’s true whether the issue is terminating a pregnancy or fighting cancer.
The act of heart surgery is of course morally neutral. A person’s choice to have a heart surgery, or for that matter an abortion, isn’t a moral question because it doesn’t impact any other person. As Jill says, the good comes from the fact that this option is available. And conversely, the moral evil in abortion legislation comes from people who pass laws that cause the maternal mortality rates to skyrocket.
