Quick question, do five people die every time I press the button or only the first time? And also, can I use the button to revive the five (or more) people I killed already by pressing the button? Because the answers to both those questions would influence my decision on weather or not to use the button.
I think at first though, knowing I would kill people, I wouldn't use the button, but the longer I kept it around the more likely it is that I would eventually give in to temptation and press it and gain the sweet sweet benefits within. After I pressed it and began wishing for video games, money, women, and more free time with which to enjoy them I would probably use my powers to get world peace and end world hunger, just to even it out.
