It is not enough to ask, 'Will my act harm other people?' Even if the answer is No, my act may still be wrong, because of its effects on other people. I should ask, 'Will my act be one of a set of acts that will together harm other people?' The answer may be Yes. And the harm to others may be great. If this is so, I may be acting very wrongly, like the Harmless Torturers.
