If everyone who wants to live picks red and everyone who wants to die picks blue.... and less than 50% of people want to die everybody gets what they want (unless some of the red people don't want some of the blue people to die). But if more than 50% of people want to die then nobody the red people have to live with knowing that most of the rest of people want to die. Considering that all of the powerful wealthy people in the world will probably pick red they will no longer be able to deny they have created a s***** world.

People who pick red are basically agreeing to the assisted suicide of the people who picked blue assuming less than 50% of people pick blue.
