"First Do No Harm"

Let's talk about reality. In California Anestheosiologists refused to take part in Michael Morales' execution. We need more medical professionals with conscience. Is execution by the State because it disuades future crime and murder and demonstrates the State's power to govern ever warranted? Doctors are refusing participation on ethical grounds that it forces them to reneg on their oath. Why is it only the medical profession that refuses to do harm? Why not civil servants? Does execution really have to be somebody's job?
