One interesting question is whether modes of agency apply differently in assessments of narrow and wide proportionality. For example, one might hold that if a person is liable to a harm, then it is morally irrelevant how that harm is brought about. Alternatively, we might think that narrow proportionality assessments should be sensitive to at least some of these moral distinctions. For example, it might be argued that an agent is liable to a certain level of harm that prevents them from posing a threat, but is liable to a lesser harm that involves using her as a means (McMahan 2009: 219–221). On this view, persons are not liable simply to a certain level of harm, but rather to a certain level of harm brought about in a certain way (Gordon-Solmon 2019).
