VIII—Two Act-Omission Paradoxes

There are two ways in which the act-omission doctrine, which implies that it may be permissible to let people die or be killed when it is wrong to kill them, gives rise to a paradox. First, it may be that when you let a victim be killed, you let yourself kill this victim. On the assumption that, if it would be wrong of you to act in a certain fashion, it would be wrong of you let yourself act in this fashion, this yields the paradox that it is both permissible and impermissible to let yourself act in this fashion. Second, you may let yourself kill somebody by letting an action you have already initiated cause death, e.g., by not lending a helping hand to somebody you have pushed. This, too, yields the paradox that it is both permissible and impermissible to let yourself kill if you are in a situation in which killing is impermissible but letting be killed permissible.
