 There are a variety of possible replies, such as that offered by Rivera-López (2016), which claims that there is a principled difference resting on the need to make moral attributions at all. We should accept moral luck where it is necessary for making the practice of attributing responsibility possible, but given that it is necessary in the case of circumstantial luck and not in the case of results luck, we can draw a principled line between the two pairs of cases. Hartman takes it that what is really needed here is that we ought to accept moral luck only if it is needed for our practices of attribution, but also suggest that it that this begs the question in the context at least without further defense. Another reply is that accepting circumstantial luck does not require accepting that it makes a difference everywhere, and that indeed Sneezy and Off-Target are themselves equally blameworthy. Thus, the analogical argument does not get off the ground with this set of cases. And yet if we turn to a different set of cases, such as the case of Jenny described earlier, who lives in a utopian world but would have collaborated with the Nazis, where the intuition of differential degrees of blameworthiness is stronger, the analogy becomes much weaker. Nevertheless, the general line of argument poses a challenge for anyone who wishes to draw a line, accepting some kinds of moral luck and not others.
