I certainly believe in the principle that abortion can be the kindest thing in some cases. But in a case where the principle problems are with the exterior, rather than the interior, and there's no chronic pain... I'd have to say that abortion seems wrong. I mean, aren't most of her problems due to how she is treated?
I've worked with cerebral palsy kids and they don't have a much worse deal. Brain is fine, but they can't control their bodies. Eyes don't point, limbs flail around, lungs fill up with fluid if leaning at the wrong angle. But they were good guys inside, and no different in how they were epxeriencing life than you or I would be if inside the same body. I won't say they had GOOD lives, but they had 'em.
