So it's better, given the medical knowledge we have now, to carry to term a baby that will have a difficult and shortened life, possibly in pain, than to end it long before they are conscious of that suffering?
Down syndrome is mild compared to some ailments. Would you want someone to carry to full term a Harlequin baby? Not even going to post the pics they're so disturbing.
I don't know what a harlequin baby is so you will have to give me an example.
and no i would never kill any person no matter what unless i was fighting a war and was engaged in the heat of battle. I don't give judgement on little children and decide which ones are "worthy" of life and which ones deserve death.
