You're on exactly the right lines. If your only chance ever to exist meant that you'd be deaf, you wouldn't have been harmed by being brought into existence, and I don't think you'd have been wronged, either. So if a parent had chosen a deaf embryo, the child it would grow up to be wouldn't have grounds for complaint.
