Virtually all of the confusion about the morality of cloning can be clarified once we answer two very basic questions, one factual and one ethical. Think of a clone as a twin. In 1993, Hall and Stillman did not create anything unusual. The process that produced Dolly was more complex, but the end result was the same. Clones are no more exact copies than any two identical twins are.
Twins are different persons with distinct bodies and souls and personalities.
The only thing they share is the blueprint by which their physical bodies were built. This is important. There seems to be a lot of confusion on this point. Cloning does not reproduce one's self, but only an identical twin of one's body. If you took one of your cells and cloned it, the result wouldn't be another one of you, but rather a twin brother or sister.
