i was speaking of creating a clone from a terminally ill or otherwise totally willing person. but not experimenting on the clones any more than the succes or no of cloning being the experiment.

But you would be experimenting on the clones themselves. The "sucessful" Dolly the sheep cloning was the result of many hundreds of deformed and aborted cloned sheep. Perfecting human cloning could well take the same number (or more) of failed attempts.

P.S. The last news I saw on Dolly was that she was aging more than normal for a non-cloned sheep, so it is difficult to see even that experiment as a total sucess.
