Red is the obvious choice from a self-preservation perspective but not a moral one. You're seeing here in these comments that there are lots of blue pressers; they would all die. This creates a snowballing incentive to push blue: people dying is bad.

There's several reasons why someone might make the "wrong" choice, and reaching 50% + 1 on blue is way easier than reaching 100% on red. And sure enough, the polls I've seen have shown blue with a majority every time.
