Your objection that killing a cloned being is UNethical is well taken, believe it or not. I'm sensitive to the unethical nature of, for example, enslaving others to be our organ donors (Chinese-style). But what if we can clone a human NOT to have the parts of the brain associated with sophisticated human thought? Then Christopher Reeve's memory lobes could theoretically be transferred to the new, more primitive version of his brain in the walking version of himself. If cloning enthusiasts can manage to make a cloned body mature rapidly enough such that Christopher Reeve could occupy the new him in adult form not long after the cloning procedure transpired, that seems all the better. Some could argue that this is enslavement, or a slippery slope to it. Would it not seem that they're
missing the picture though?
