When I was thinking about this I was thinking more of like incidental contact, not so much intentional / artificial. I suppose then I have updated my opinion and now think it is irresponsible to begin the process without a clearly defined end point at a minimum.
However, there is also obvious life-saving research performed in these scenarios, and the utilitarian aspect is tempting to examine.
One thing that came to mind was a single cell such as in an identical twin - if the other goes on, but the twin is used for research and destroyed, where does that leave you? I think I would have to say that was a unique human life that was ended.
I honestly don't know where this leaves me with regard to IVF in general, because as I understand it there are usually excess embryos, right?
