Abortion in the times of Down Syndrome and other disease diagnosis

Recently, I read this interesting post in the Freakonomics blog that really worth it.

As a parent, I have found that the greatest pleasures are in watching your child achieve a goal. (...) My guess is that the underdog nature of a child with Down Syndrome makes the little accomplishments that much more satisfying for their parents.

I think we are no one to take the decision to put an end to an innocent life, not even if this child has a problem or a disease. Of course, it's not easy to assume that you have to rise a child with a problem, but again, probably is the most important thing you will do in all your life.
