Are abortion bans like mandatory kidney donations? Part 3

Framing abortion bans as comparable to forcing someone to donate a kidney overlooks a crucial moral difference between how much help someone must give and whether they may directly kill another person. In contexts like car accidents, the law can impose obligations on someone who caused harm—such as paying damages or covering medical care—and there is debate about whether those obligations could ever extend as far as organ donation. But even where the law allows a person to withhold further assistance, it never grants permission to kill the injured victim. Refusing extraordinary aid may leave the victim in their injured condition, but it does not itself constitute an act of lethal violence.

Pregnancy is different in a morally relevant way. A fetus’s continued life depends on ongoing gestation, so ending that gestation does not leave the fetus unharmed or in a neutral state. What is sometimes described as “refraining from helping” in pregnancy necessarily results in the fetus’s death. For that reason, abortion cannot be understood as mere non-assistance analogous to declining an organ donation. It is an intervention that brings about death.

Because abortion inherently involves lethal actions—such as suffocation, lethal injection, or dismemberment—it is not comparable to choosing not to donate a kidney. The analogy fails because abortion does not simply decline to rescue someone already dying; it actively kills a developing biological human being. As a result, abortion bans are better understood not as mandates to provide extraordinary aid, but as prohibitions against intentionally causing death.
