And the left says: "You know...that argument makes a lot of sense..."
He indicated he would do so "if that was in the best interests of the baby and of the family as a whole."
OK what makes someone think that they know the answer to this. Not even the parents can always know what the worth of the child may be at the moment they try to make such a decision. This (The death of the child) may be later found to be the wrong decision if the child is allowed to live and grow. You would have to be pretty arrogant to believe you can know the answer to such a question.
