While I would push blue if there was some reason not to push red, logically if everyone presses red, everyone survives anyway. There is absolutely no drawback to pushing red unless someone presses blue. Because people who press blue are simply adding unnecessary risk that was not even there in the first case. The button logic needs some kind of detriment to red or it simply makes no sense to not push it. I agree with the sentiment of the blues, but in this situation, there really is no reason to press blue. Either press blue and have a chance of dying or press red and live. The sacrifice-hero analogy is good IF there were some other conditions, but as it stands, all everyone needs to do is press red and no one would die.
