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.

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.

The bad outcome for choosing red is that people that choose blue die.

Or blue doesn't want to live in the world where only selfish/cynical people remain.

I would personally assert it's foolish to pretend a species can survive without empathy and mutual aid. That's certainly not how humanity (or most, if not all, species) developed so far: https://en.wikipedia.org/wiki/Mutual_Aid:_A_Factor_of_Evolut...

There's actually many scientific studies which tend to show that empathy is inversely correlated with wealth. That's popular knowledge as old as class war, but it seems there may be scientific evidence to support that.
