Like I mentioned earlier, there is no defined moment of transition, with respect to time, when the embryo stops being a living entity.
This is too easy. I'm confident in saying that in an infinite number of years, none of those embryos will be alive. Those never used will have been killed.

Your confidence is no substitute for actual proof. Since the transition is more-or-less random and unpredictable, it can be assumed an act of God that killed it... just as in the case of people in vegetative state, hooked onto support-machines, based on the earlier arguments made by the theologists here.
