Question: Why would the clones receive brains? Why not just leave them in a coma-like state? If you would replace the owner's brain, then the owner wouldn't be the same person, even if you'd rewrite it. You could say that you could replace part of the brain only, but even in that case, the clones could be kept in a drug-induced coma.

Answer: Merrick explains (albeit briefly) that the clones needed "human emotion...life" or the organs failed.
