The dilemma is that there are some people who are not smart enough to understand this and will press blue.
If you want a dilemma, it must be inside the model, for example: a 10% of the buttons are miss wired, and the system register the oposite color
So if red wins, at least 10% die. If blue wins, everyone survives. Now you have a dilemma. Which button would you press?
PS: If a country has 20 cities and one of them has a big majority of red-pressers, is it moral to nuke it out of existence?
Though in a sense, i agree it's not really a dilemma because only sociopaths pick red in real life. See also intense and spontaneous cooperation in times of crisis (catastrophe, war, etc).

> the numbers disagree with you
It was a pool in X where people that press blue were not going to die. They just lied to feel better.
Try again with money, everyone puts $1000 so it's real but nobody dies. Red pushers get their money back, everyone if >50% press blue. I like my version where 10% have miss wired buttons, so the % of people that will vote "incorrectly" is inside the model. Send the lost money to an Khmer Rouge advocacy group so nobody feels good about losing the money.
