Let's imagine that you are the director of an in vitro fertilization clinic and that you are faced with the decision of destroying hundreds of fertilized eggs -- for whatever reasons there may be. Faced with such a decision, it would be preferable to decide in favor of life to enable those stem cells to continue to survive as new heart, pancreas, or nerve tissue to prolong the life of a patient with heart disease, diabetes, or Parkinson's disease. I see no moral problem in making such a decision. The fate of a fertilized egg depends on where it is placed. If is is not going to be placed in a uterus to enable it to grow to form a new person, why not place it in another environment where it can remain alive and still benefit human life?
