If you take the case of sickle cell anemia, you’ll find this is not the case. You need to understand more about genetics and why these mutation survive over generations. They don’t survive by accident they survive because when they are heterogeneous, they are beneficial to the population. It’s only the unlucky child that ends homozygous that will suffer from illness. But that is the balance and sacrifice nature makes to keep a population alive. It’s indifferent and amoral, it’s utilitarian. And it’s way beyond the comprehension of human knowledge.
