Political morality has to be derived from scientific analysis of human goals and desires. There is no god to help us with this.
Here is a human problem: there are so many of us that our waste products are destroying the stability of our environment, pointing to the possibility of population crashes in the billion person range.
Everyone dies, usually after less than a hundred years. During that lifetime, I think people should enjoy a moderate homeostasis consistent with individual freedom to choose and act on choices.
Gross eugenics is called birth control. It is resisted by mainly religious interests, who seem to care little about the lives of those in the here and now, preferring (I guess) to concentrate on the location of souls in the future depending on our actions in the present, and birth control being evil and against gods' wills, therefore not acceptable.
But humans are the result of a selection process that has rewarded the fight for survival, as it has increased our mental capacity to where we agonize about the choices we must make to stay alive and comfortable in our fashion. Which tendency will win?
Now we have a situation where everyone on earth cannot live the life they wish to live, and strife is breaking out, condemning large numbers of people to brutal short lives.
Can we change our moral capacity through genetic engineering, as we do through pharmaceuticals?
We have pills for aggression and depression. Can we genetically modify humans to slightly change their tendencies to act anti-socially? To have minds more rational and less emotional, maybe a mild autism?
I'm aware that genes are complicated, that sometimes a single expressor controls dozen of other genetic flowerings. I am sure that more will be discovered.
We need to think about this before it happens. It's a touchy subject. Please behave rationally and politely.
