Morality of Designer Babies

Designer, or test tube, babies, in my opinion, are simply tools created by their parents to save, the obviously greater cherished, older sibling. No matter if the parents wanted another child or not, the baby was created for science and the advancement of science. Science is advanced enough already. We humans continue to screw up the natural order of things, and the more we do it, the quicker our world dies. Disasters and diseases exist for a reason, and should not be tampered with. Think of how these children feel! They must feel unwanted and manipulated, less loved than their older sibling. Designer babies should not be utilized any longer.
