I assume most people are aware there will be some blue voters. I also assume that greater than 50% of the population are more socially minded than not as if it was otherwise, in the long run the society would fail to stay cohesive.

It would be easy to self justify picking red as 'it's not unethical killing, it's self preservation' but I'd still bet on society being more socially minded than not, for betting otherwise would mean i think society as an idea of togetherness is a total illusion. If choosing red, after, it would be non existent.

Though also to me the experience of life is starkly temporary; dying early or not doesn't really matter to me so i'm not surprised other's emotional conflict varies here. But as a result personally, losing the existence of something unique to experience (togetherness) in preference of something otherwise fleeting, even the self, isn't very interesting to me.
