I mean, it's a bit the dilemma posed in Brave New World: what if we can create a veil that restricts our views / thoughts, but in exchange grants us happiness? When someone, for any reason, breaks out that veil, the realization that happiness only exists behind the veil and the lies is quite shocking and unacceptable for us as humans: the very realization that our happiness is built on top of lies will make us unhappy, and seeing it from the outside will often make us claim that that's a false/fake happiness. But then, what about religion, or blind optimism, or the innocence of children? About ignorance itself? Is it acceptable to let people choose their own veils, but not to have them imposed? And if everyone accepts a certain lie, is that fair to the remaining minorities? That's what happens when you let evolution run wild. We might have the desire to be good to others and ourselves, but we don't have the power to go all the way through.
