Just to be on the same page. The child is not "created" and then "implanted" with the disability. The embryo with the disability is picked to be born. So it is not unethical to the child (the other option for him/her was to not be born).

True, but the result is the same whether the child was "picked" from an embryo with a disability or if he was born fine and then the parents injured him in a way that gave him the disability, which would be considered totally despicable and illegal.

No, the result is not the same. It's a choice between life with deafness, or death as an embryo so that a sibling can live instead.

[Houshalter]

The result is a sentient being with a disability. It doesn't matter if a mutation caused it or you physically injured the child, the consequences are the same.
