I completely agree with the "design" baby discussion. I agree because the baby is still serving a purpose in life and will be loved by it's parents no matter what. The argument about the parent not loving the child because it was selected to help the older child is irrelevant. When two adults have a kid unplanned they don't pretend to love it they do. It's the same thing with "design" babies because the parents will still love them and the child will serve a purpose in life and be proud for saving it's brother or sister in life.
