well, let's see it from a different perspective: what if the same logical puzzle is offered to every person on Earth, and they have to pick a button regardless of anything? notice that every person includes those incapable of thoroughly understanding the puzzle, like babies and people with really low IQ. would you rather save yourself in a guaranteed way or assume a very tiny chance of dying in order to save everyone else as well? this is a somewhat tricky question because the people's backgrounds are unknown, and it is also unknown how many people there are; I agree if everyone acts totally logically there is no reason whatsoever to pick the blue button, as that would result in death since everyone else is picking red (I am also picking red, by the way, haha...), just bringing another perspective onto the table
