 Non-contractualist deontologists and direct- or act-consequentialists tend to prefer the interactional approach. Their central question is: what moral reasons bear directly on the permissibility of killing in war? This focus on killing might seem myopic—war involves much more violence and destruction than the killing alone. However, typically this is just a heuristic device; since we typically think of killing as the most presumptively wrongful kind of harm, whatever arguments one identifies that justify killing are likely also to justify lesser wrongs. And if the killing that war involves cannot be justified, then we should endorse pacifism.
