The equality objection claims that Marquis's argument leads to unacceptable inequalities. If, as Marquis claims, killing is wrong because it deprives the victim of a valuable future, then, since some futures appear to contain much more value than others—a 9-year-old has a much longer future than a 90-year-old, a middle class person's future has much less gratuitous pain and suffering than someone in extreme poverty—some killings would turn out to be much more "wrong" than others. But as this is strongly counterintuitive (most people believe all killings are "equally" wrong, other things being equal), Marquis's argument must be mistaken. Some writers have concluded that the wrongness of killing arises not from the harm it causes the victim (since this varies greatly among killings), but from the killing's violation of the intrinsic worth or personhood of the victim. However, such accounts may themselves face problems of equality, and so the equality objection may not be decisive against Marquis's argument.
