It’s not a complicated question. You hold the gun, target in the sights, finger on the trigger. An innocent, no question. But the stakes could not be more clear: one or one hundred. Either you kill this one person, ending their life and putting their blood on your hands, or you do nothing, and one hundred die through your inaction. Is it morally permissible to fire? Is it morally permissible not to? You could ask them first, I suppose – are they willing to die for the sake of one hundred strangers? That would certainly be noble of them, and possibly clear your conscious. But what if they say no? What if the stakes are one thousand strangers? One hundred thousand? One hundred billion?
