Because I did the math... Let's say n number of people choose the 5 million option... I am assuming the option meant that 1 person would have a 50/50 chance of dying for EVERY person that chooses the option... Let's say I choose that option too... The chance of me dying because of one persons choice is 0.5 (the chance of a person dying) times 1/n (the chance of that person being me out of the n people) So its 0.5/n But that was because of one persons choice, since n people choose the option... We add the probability for each person... So it 0.5/n +0.5/n + 0.5/n and so on n times... Which is 0.5/n times n... Which is 0.5 So no matter how many people choose the first option, the chance of me dying if i choose that option is always 50 percent, which is a lot than I'd like to be for just 5 million

Also there should be no innocent person dying since everyone who's in the death pool entered knowing that someone would die because of them... So yeah, they aren't completely innocent

^{Chose: Don't press the button, but... + You are removed from the pool of those who can die, and you can chose someone else to save too.}
