We cannot make value judgments as to who should and should not be marked for death or for salvation  Different people’s lives may indeed weigh differently. Some people may go on to cure cancer, while others may become serial killers. However, we do not know who will do what with their future, and it is an act of immense hubris to perform calculations that presume otherwise. We could be killing future a serial-rapist in order to save future a philanthropist who funds Somali famine-relief, but we could just as easily be doing the opposite. We are in a state of incredible ignorance as to what these individuals will choose to do. It truly is to “play god”, and vastly overestimate our ability to judge who will be good for the world and who will be bad.
