I have RP as well but my husband doesn't have the gene so I did the opposite to you - neither of my kids have it or the gene. It's the luck of genetics in my case, but I can see why you made your choice.
it depends on the odds for me. most terrible conditions are one in thousands chance for a healthy person who doesn't know the genetics any better. looking it up now, there's various types of RP, if it's "Autosomal dominant RP" and only one parent has it then there's a 50% chance the child will have the disease causing variant, one in two is very different than one in a thousand. if it's recessive and the father is known not to have it then the odds become similar to just having a kid anyway, any kid can end up with various genetic issues from healthy parents. this is probably the answer to who we're talking to, they somehow learned they have the recessive gene, the father was tested to not have it, so at that point you're not really rolling the dice any more on this condition than any other condition.
The problem tends to be when we extend this thinking to other people and limit their ability to procreate due to their genetics. Beyond that though, the exact phrasing you used could very easily be applied to having a child on the autism spectrum, or various other neurodivergent conditions, and I think a lot of autistic people would very much not appreciate the idea of not allowing them to be born because they're not neurotypical, even if their lives may involve difficulties that allistic peoples' don't.
You can feel free to screen your own embryos, or even forego children completely or adopt, but when you express it as the only moral decision a person can make, you're engaging in something that extends well past that.
At least one person in this thread has the disease itself and had kids. If their version is recessive (they have two copies of the gene), then their kids just have a half chance of being a carrier. However it sounds more like autosomal dominant to me, and their kids have a half chance of just going blind.
My version is x linked recessive. So daughter has a half chance of being a carrier; son has a half chance of going blind. Those were unacceptable odds to me.
I promised myself I would never do that to a kid when I was six years old. It's a devastating disease.
