PS. Working with fertilized eggs and extracting stem cells in the process is not causing harm, it is helping people.
I see so if I kill you before you have developed enough to know you are being killed its all good as long as I use your parts to help others?
You have fully embraced the modern narrative of death.
It is sad that you cannot understand that knowledge gained at such a price is a Faustian bargain.
If you kill a fertilized egg that could eventually become me, assuming you could find a suitable uterus and successfully transfer the egg, you will be killing an egg not me.
Personhood comes much, much later. Even at birth, you are not you. You become you as your brain develops. It is not an on/off but a continuous process.
If you take your brain and somehow duplicate it in another body, after 20 years, the two of 'you' would not be 'you'. You will be you but the other 'you' will become some other guy.
Your assumption that a fertilized egg is a human being is ridiculous. Who told you that a fertilized egg is a human being? Whoever did that, knew squat about human biology. And you think you are a medical doctor?
As for your poetic reference to the Faustian bargain, well, I don't know what soul is, so I don't know what mythological mumbo-jumbo you are talking about. As for morals, my morals are superior to most of the Bible book club members.
So which website will CoinCube find next to convince himself that he is right?
