International Humanitarian Law mandates that all wounded in war, no matter which party they belong to, shall receive aid in accordance with their medical condition, and that “there shall be no distinction among them founded on any grounds other than medical ones.” This principle of impartiality is endorsed by various other military and civilian institutions worldwide to include the ICRC, the US Department of Defense, and the American Medical Association. In this essay, I argue that in some cases, we ought, (...) morally speaking, to triage based on factors beyond one’s medical condition. More specifically, I argue that in these cases, we ought to triage, at least partly, based on one’s moral responsibility for one’s current medical predicament. I call this view Triage by Moral Responsibility (TMR). I support my argument for TMR by demonstrating its plausibility when applied to cases of medical treatment and disaster relief, and by drawing parallels between these situations and those considered in the ethics of defensive harming. I conclude by discussing the practicality of my moral conclusion for the practice of medical triage in pandemics and war. (shrink)
