To be used as raw material for the pharmaceutical industry is not what gives meaning to the existence of a human embryo. That meaning is inherent in the act of creation and we choose either to respect it or not. All human beings eventually die and embryos are no different. The moral evil is associated not with the fact that embryos die, but with the fact that somebody decides to kill them. No advances in the treatment of disease justify the deliberate destruction of embryos irrespective of the benefits involved or whether other sources of stem cells are equally useful. We cannot cross the principle that a good end does not justify evil means. I believe embryonic stem cells should not be used for research.
