Negative natural selection or purifying selection is the selective removal of alleles that are deleterious. This can result in stabilising selection through the purging of deleterious genetic polymorphisms that arise through random mutations, purging of deleterious alleles can be achieved on the population genetics level, with as little as a single point mutation being the unit of selection. In such a case, carriers of the harmful point mutation have fewer offspring each generation, reducing the frequency of the mutation in the gene pool
Modernity has inherently weakened negative natural selection by allowing individuals with traits that would have been detrimental in the past to survive and reproduce, Those individuals's genes are harmful to the population; diseases like Sickle-cell, cystic fibrosis, Tay-Sachs, etc. wouldn't have existed in such numbers without technology.
Is it worth it to treat those diseases? and prolong people's suffering at the risk of spreading such genes to the next generations, I recently read about a baby in UK who was suffering from a mitochondrial condition, she got removed from life support, This baby wouldn't have existed or been brought into existence without modern assistance. To be fair, in some cases, doctors use reproductive technologies (ART) with genetic testing to avoid passing the mitochondria's genes to their children. But that's only one case, what about the other numerous diseases.
Humans are literally forcing life on other humans where existence itself won't allow it. I don't know what men become anymore, sacrifice tribes were more morally adjusted than us. Only for the sake of their machine's utility. We are willing to maximize suffering.
