Gene editing beyond treating diseases quickly boils down to doing animal experiments on humans. Imagine that the gene editor made a mistake and now the test subject is missing the left ear. How do you deal with these "defects"? Of course! By putting them to sleep like regular lab animals.

Of course there is nothing inherently wrong about doing experiments on humans but the problem is you now need to justify that gene editing is good and eugenics is bad, that the test subjects do not need basic human rights and therefore can be disposed when convenient.
