The Doctrine of Double Effect (DDE) provides that, all else equal, intentional deaths are harder to justify than merely foreseen deaths. The principle is meant to ground the distinction within humanitarian law between terror bombing and strategic bombing. However, according to the “closeness problem,” terror bombers are not necessarily intentional killers. Terror bombing strictly requires only that the civilians appear dead, goes the argument, such that—for a “sophisticated” terror bomber—the civilians’ deaths could be unintended side-effects of making them appear dead. But if intentions could be calibrated so finely and strategically, the argument continues, then the DDE would very doubtfully be true. This essay replies to the closeness problem in three steps. First, agents often intend _causal processes_, with specific causal “ingredients,” as the proximate means of bringing about their specifically intended means or ends. Second, when an agent foresees a byproduct as resulting directly from their intended causal process, it is morally equivalent to a specifically intended outcome. The process’s causal relationship to the byproduct is constitutive of the process from the agent’s perspective. Third, a “sophisticated” terror bomber’s intended causal process involves blowing up the civilians, while a strategic bomber’s involves blowing up, say, a munitions factory. Thus, because the “sophisticated” terror bomber foresees their intended causal process as resulting directly in the civilians’ deaths, while the strategic bomber foresees their deaths as side-effects of their intended causal process occurring within an environment that happens to contain civilians, the DDE can distinguish between the bombers.
