Sorry, one more point about that line of thinking. If we WERE able to predict who every kid would become, does that suddenly make abortion alright in your eyes?It depends. If it´s Baby Hitler, i´d choose the suitcase. If the suitcase is full of supremacist titan_tim fetuses, i`d save an old man who is has less than a minute to live.
If you predict that the baby would be a murderer, you'd be alright with abortions for any murderer babies? What about all the babies that will be drags on society? Are they alright to remove from your carefully weeded out society? You'd pick out only the ones which go on to become the best of society? That's pretty dark.
