Ace, to the Church, there's no difference between that embryo and an adult human being.  Both are equally and irrevocably human.
Rictor, whether self-aware or not, both forms of life are human, and thus the Church's writings are the way they are.  There's no warping going on:  the Church does not agree with cloning under any circumstances.
Vyper, I would not take an innocent human life to save my own.  Nor would I pursue an unrestrained field of study, as too many scientists seem all to eager to do nowadays.  If I did have diabetes, I would live with it, as millions of people do every day.  If a relative had a neurological disorder, I would pray for them and do whatever I could to support them, but I would still not resort to killing embryos.
