Two Types of Mad Scientist

The debate over embryonic stem-cell research can be summed up in two quotes from The Man with Two Brains (mentioned in another context at The Volokh Conspiracy). Supporters of stem-cell research think they're saying:

Dr. Michael Hfuhruhurr: The only time we doctors should accept death is when it's caused by our own incompetence.

Opponents of embryonic stem-cell research hear them saying:

Dr. Necessiter: Nonsense. If the murder of twelve innocent people can help save one human life, it will have been worth it.
