Full title: John C Woods, hangman of Nuremberg trials, who lied about his experience to get the job (he actually learned about hanging from old cowboy films). His lack of expertise led to excessive suffering of condemned Nazis.
This kind of rhetoric is extremely harmful, as it encourages people to not critically examine the moral impacts of their own actions. Nazis were people. If you believe that only evil people do evil things, and that you're a good person, you are priming yourself to excuse any atrocity you might enact or support.
