Q1-Are there any moral acts that are in themselves so bad, awful, disgusting or downright wrong that they should never, ever be done, regardless of the actor's intentions and the act's consequences? And what is it about such absolutely bad acts that makes them so bad?

Q2 Have you noticed any instances of professionals doing what they regard as their duty even when their actions have resulted in negative consequences? Please describe (although you don't have to name names). What authority has given them the idea that they are under such an absolute obligation?
