^^ That reminds me about how they explained the Reavers in Serenity
. They introduced such-and-such into the water or atmosphere (or whatever, can't remember exactly) to make the population more docile and less prone to violence, but it backfired and people stopped doing anything
and eventually died of starvation or whatever. The rest of the population had the opposite effect and became the violent, cannabalistic Reavers.
Moral of the story, don't help humanity be better. It only makes it worse.
