Embryonic Stem Cell Research (read) TV

I have been reading about Embryonic Stem Cell Research, and it is a very helpful new discover in the world, but it could also be bad. The way they use the Embryonic Stem Cells is they get unused embryos and fetus' of aborted or miscarried babies. I think this could be bad and good. Bad because they are pretty much sacrificing the embryos and then we get to benefit. But it can be good because it can help with alot of diseases that we need to help with because as we get into the future we see more and more of it.
