Couldn't agree more, we had a same discussion in 12th grade not directly a deformity but indirectly relates to that too, we talk about gene modification in our biology class all agreed to do so if it will make the lives of offspring easier by decreasing the chances of major deadly diseases, abortion is another matter though but If I'm questioned I'll abort the baby right away and also if I discover that I've gene problem that increases risky diseases that is not curable I'll decide to not have a baby in my entire lifetime, if you remove ethics and moral dilemmas regarding abortion it's not that bad actually.
