Magically, you travel back in time to September 10, 2001, to a soundproofed room where all the 9/11 hijackers are sound asleep. You have a gun, a silencer, and a plenty of rounds (bullets) left. But they haven’t done anything yet. Do you kill them? Why or why not.

In September 10, 2001, here I am with the hijackers who caused the massive destruction to the world trade center by travelling back in time. I am caught up in their midst either to kill them or make them destroy the world trade. To me I will kill every living soul that took part in the planning of destroying the world trade center.

It all happened when magically I appeared in a soundproofed room where all the 9/11 hijackers are sound asleep. That was before they were trying to invade the world trade center and kill thousands of innocent people. Apparently I had a gun, a silencer and a plenty of bullets to kill them all so as to prevent the incident from happening. Because I happened to be among their midst on 9/10 and this is a great opportunity for me to save the world. I will kill all of them from causing a massive destruction to the world trade center and saving thousands of innocent  people. 

Because at that moment there is nothing i can do to turn them to the police . In the first place i magically appeared in their midst when they were about to cause the disaster , which is there is no possible way for any other person to believe me . Killing them will save the world. I will be a secret hero .

In conclusion , even though no one will see me as hero of saving the world . At least i saved thousands from losing their lives from the hijackers.
