If you knew you could pass a genetic disease to your children, would you want to be allowed to use gene therapy to “fix” the gene before the children were born?

It depends on if the gene therapy would do something to the gene that could harm you. If there is no harm to you or the children then It seems logical to do it so the children do not have the disease. Because it is a genetic disease, if you "fix" it there is a higher chance that the children will not pass it on to their kids
