How many babies is Christopher Reeve worth?
Are you kidding me? This is ridiculous. Stem cells used in research are retrieved from a stem cell bank. Stem cells comes from blastocysts which cannot develop into embryos or fetuses unless they are implanted in the uterus. So you are not killing any babies to save a life, since the baby does not and cannot exist unless it is implanted in a woman's uterus!
Your question was poorly and inanely phrased.
And even if they did, those babies were always going to be aborted, might as well use them to help others.
