 The claim that bringing into existence a person in a harmed state according to a certain threshold is wrongful implies that this person is worse off than she ought to be. That the person will have a life worth living is not a sufficient reason to render permissible bringing the person into existence and in a harmed sub-threshold state. The ground for this reason does not rely on a comparison with how well off the person or other people would be if we refrain from bringing the person into existence or acted differently (but see Harman 2004: 101–102; McBrayer 2008: 304; Woollard 2012). The reason understood in person-affecting terms does not reflect the view that the person would be better off if he or she would never ever come to existence or the view that we should bring into existence another person whose life is above the threshold or the view that we should maximize the number of people with lives above the threshold. Rather, if we have a choice between bringing into existence a person with a life worth living, but below the threshold, and bringing into existence a person with a life worth living at or above the threshold, the reason, namely, that persons can be worse off than they ought to be, speaks against doing the former but not in favor of doing the latter. This is how we can argue on the basis of a weak person-affecting view (see  §1)  and a threshold conception of harm (see  §3).
