I. Therapeutic cloning - somatic cell nuclear transfer does not occur in nature, as far as I know. Therefore you are not interrupting the natural course of events. SCNT requires a causally significant act - implantation - in order for a child to develop. However, the destruction of a pre-embryo could be construed as a causally significant interruption of the development of human life.

II. Reproductive cloning - you are creating a human life, not interrupting it, in the case of embryonic stem cell research. This is supposing that you consider a pre-embryo a "human life".

III. The "argument" that cloning is repulsive is not an argument at all. It is stupid.
