Capital punishment is a good example, but also an extreme one, and slightly tangential. It isn't that doctors oppose capital punishment for the reasons the anti-capital punishment movement does (the government shouldn't kill people, mistakes are made, the sanctity of life, etc.); instead it is simply because it violates the doctors direct "do no harm" oath.

And it is a rare corner case. Overall, there are plenty of doctors across the political spectrum. I mention this because the ethics proposed in "Never Again" are not like that. They would need to be changed quite significantly to be. That's the issue here.
