Without forming complete organisms the stem cells can not save any lives. When in Blastomere stage and extracted cell is not perfectly capable to form complete new organisms on their own. “Presently there is no evidence that a single stem cell, once replication has begun, has "the intrinsic capacity to generate a complete organism in any mammalian species" when extracted during the blastomere stage” (Embryonic Stem Cell Research Poses Ethical Considerations) Thus, If we are not sure that embryonic stem cells have the cure, we must not start killing
