 Condition (b), however, is far more knotty. For what is it to intend that death result from one’s behavior? There are examples in which condition (a) is clearly met, but whether (b) is met is more problematic. For instance, does a soldier who leaps upon a live grenade tossed into a foxhole in order to save his comrades engage in suicidal behavior? Many, especially partisans of  the doctrine of double effect  would answer ‘no’: Despite the fact that the soldier knew his behavior would likely cause him to die, his intention was to absorb the blast so as to save the other soldiers, whereas his death was only a foreseen outcome of his action. Needless to say, whether a clear divide exists between foreseen and intended outcomes is controversial, and critics raise the worry that almost any outcome can be described as foreseen (Glover 1990, ch. 6). (It is of course possible that whether death is foreseen or intended has no bearing on whether an act counts as suicide but still bears on whether any particular suicidal act is justified.) Some would argue that given the near certainty of his dying by jumping on the grenade, his death was intended, for even though death is not the justifying aim of his action and he may prefer not to die, his dying nevertheless has his endorsement in the circumstances in which he acts (Tolhurst 1983, Cholbi 2011, 26–31). A further complication is that current psychological evidence suggests that suicide is often an ambivalent act in which individuals who wish to die must nevertheless overcome the ordinary human fear of death (Cholbi 2011, 31–34, Joiner 2010, 62–70). Given this ambivalence, whether an act that posed an apparently lethal threat to the agent who performed it was intended to hasten her death can be hard to decipher. When a person dies in such circumstances, it may prove difficult whether to classify the death as resulting from suicide (i.e., intentional self-killing) or as accidental. Such cases might indicate the need for a third category besides intentional suicide and accidental death (Cholbi 2007).
