Blue side definitely includes the population of people that would rather die than live in a world without blues and fully understand the consequences of that choice.
On the other hand, maybe a world where everyone who is bad at game theory is dead is a better world to live in, regardless of how nice or empathetic they are.
The “chose blue” option weaponizes empathy to get people to make a counter-productive choice. If everyone follows their own rational self interest, then everyone wins.
