When does it become unethical to kill a living creature, and when a living creature becomes a human being are two seperate questions; I think most people would agree that it is fairly unethical to kill a living creature that is not causing you any harm, and the killing of it does not produce any personal benefit, long before it becomes a human being though ... |
If sperm were identical to single celled amoebas you would have an amazing point. However they are not, so your definition has a hole right there. The bigger hole is that we do not consider all parasitic creatures to be alive by default. Viruses are not considered alive for example. Taking the requirements for what is considered alive or not on the special level and applying it to an embryo simple does not work.
