People are irrational. I guarantee it’s likely that a lot of people would actually do it.

Not at all. If the majority of people can’t be bothered to press the button that says “nobody dies as long as half of the other people say nobody dies” rather than “you don’t die,” I’m happier not being around. It’s purely selfish and blue is a win-win.
