A kidnapper has taken a victim in a building. You are the guy in charge of the operation to rescue the victim. One of your elite marksman informs you that he has a clear shot to kill the kidnapper. Any other option would result in the victim being dead X% of the time, while (100-X)% of the time, either both would end up alive, or the victim ends up alive and the kidnapper dead anyway. ---------------------------------------------------- How high would X have to be for you to give the order to take the shot?

Imagine you possess the ability to know with perfect accuracy the probability that one person would commit a crime such as murder or rape during his life. You also possess the ability to instantly and remotely put to death anyone you want. -------------------------------------------------------------------------------------------------------------------------------------------------- Each group will be given a probability (90%+, 80%+, etc) and a number representing how many people are in that group (only adults are considered), for a total population of 6 billions people. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------A 80%+ probability means that each member of the group have at least a 80% chance to turn into a murderer or rapist during his lifetime, and therefore at most a 20% chance not to. For every 100 members of this group at least 80 will turn into a murderer/rapist, and at most 20 won't. The 90%+ group is therefore included in the 80%+ group, included in the 70%+ group, etc. Cases of self defense or accident are not considered. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Using your ability means potentially preventing victims to be murdered/raped, by killing potential perpetrators. --------------------------------------------------------------------------------------------------------------------------------------------------------------Would you choose to use your ability at all, and if you do, where would you draw the line?

What factor was more relevant for you to make your choice?

Would it make a difference if we included all ages in the goups (children included)
