You are given the option to kill as many people as you would like within a 24 hour period with whatever method you choose. (Having them all grouped up in a room and sucking out all the air is an option). The people are of your choosing, and can include anyone currently living. No investigative body will ever be able to discover you, the investigation will magically not cost money, and no Diety that you do or do not believe in will alter judgement on you due to this murder. As another rule, you must actively participate in the murder, though simply pressing a button or flipping a switch is enough participation. They must die within the 24 hour window of the option, and diseases that take longer than 24 hours to kill someone aren't allowed. Would you use this option to kill someone?
