Were the Nazis Just Unlucky?

In our discussion of Nagel's "Moral Luck", one of the main points that we considered was the idea that being a member of the Nazis was somewhat circumstantial and that, had someone who was a member of the Nazis lived in a different part of the world, he or she might have lived a blameless life. Likewise, a person who had lived a peaceful, seemingly moral life might have been a Nazi if he or she had been given the opportunity or put in the same situation as the members of the Nazi party. I think that while circumstance definitely has something to do with our actions insofar as morality is concerned, I do not believe that it is the only factor in determining how we will act in a given situation. If it was the case that all of morality was simply a matter of being in the right place at the right time, so to speak, then what would be the point of even trying to act in a way that we perceive to be moral, since everything would be at the mercy of chance? I think that instead of morality being a matter of luck, it is something that is internal and must be practiced, almost like muscle memory in a way. The more we train ourselves to act in accordance with out beliefs about morality, the easier it is to adhere to our principles and act morally in the future. Since so many of our moral decisions are made in a split second, or are based on a gut reaction, if we have practiced our moral beliefs enough, then acting in a way that does not compromise these beliefs is likely to almost be a reflex. So, going back to the example of the Nazis, I believe that while circumstance and luck was definitely not on their side, it is not the case that these were the only factors concerned in their participation in the party. Had they practiced adhering to their values to the extent that their moral beliefs were always in view, they might have led very different lives despite their location and bad luck.
