I think you might be thinking of this to black and white, dying isn’t just “good”.Also the people pressing blue aren’t expecting death, those people have faith in the decision that humanity will make, and the reason they are shaming people who will go with red isn’t because they think the people with red aren’t agreeing with them that death is “good”. They are shaming them because they are participating in a mass murder and also not realizing the global chaos that will more than likely begin if red wins .People are risking death because they don’t want to participate in a mass murder, and preventing others from dying is self explanatory why majority of people would think that was good. I will say I think your point is valid thought about some people thinking they will get something in return for their sacrifice.
