People: please realise that stem cell research at the cost of embryos, is wrong, plain and simple. If u have a discrepancy with the idea of an embryo as a human being, perhaps this will register with you, as it occurred to me the other day:
Human beings are -like the embryos we determine as beneath humanity- are a collection of cells at any point in our lives. Human beings renew themselves completely around 3-4 times in the course of an average lifetime. If this is so, what defines us? what binds all that together so that humans maintain their humanity? The religious call it the soul. The inconvienient truth? no amount of science can convict a man of his own respective essence. But, we cant prove the soul does not exist either, and science is emerging now, adapting to this idea of a threefold humanity (body, soul and spirit) though in denial of religion. Hypothetically speaking, if a ‘god’ were to exist, as the great end all over us, what right do you have, Oh man, to exert your desires over another? To take life to save life? further, If those who are purely scientific do not acknowledge a soul, as science cannot prove it, can they not acknowledge -at least in other areas- the limits to scientific proof? why not in this area? and further, hypothetically speaking, if this ‘god’ is to exist, calling that man shall not murder, do you, oh man, think you should tempt the unknown? You don’t know when exactly this “soul” becomes present in a human being, this deeply human atrribute; inasmuch as you dont know exactly when this attribute leaves him (which makes much trouble at the other end of the scale also, with comatose patients): if you dont know, then isnt the wisest thing to do in your ignorance and humanity is to not risk it? not to tempt fate? not to defy God?

And of this morality test, what are you exactly saying: that there are 100 fetuses floating in jars? that there are 100 pregnant women upon the third floor with unborn embryos inside them? your analogy is not plausible. However, i gather the effect of it and what you mean:
the person who placed that “test of morality,” you put yourself in that position: time is not a factor, you would do your best to save both parties in your humanity, not spending precious “time” deliberating who to save, playing God: that is exactly what these scientists do, justifying death at the improvement of overall quality of our lives: would you consent to a plot of prime real estate in an African country, at the genocide of a tribe that has lived there for generations. Don’t you dare belittle human life!!!
