National Socialism was attempting to create a Weltanschauung in which all aspects of everyday life would have a code of ethics. In many ways, it was a very romantic movement - a return to Blut und Boden, honoring your ancestors, and returning to medieval aspects of chivalry, bravery, and honor. At the same time, the government should play a role to ensure that an economic system is designed to encourage and foster this return through a progressive turn. That means, you should have the advantages of the past while enjoying the positives of the now. In essence, this idea would have been perfect if it had not been taken to extremes.
Alas, it WAS taken to extremes - to greater extremes than we have ever known...and combine that fact with the fact that these were times of great unrest and unprecedented development - it was a recipe for disaster.
Had these ideals been implemented EARLIER it might have happened peacefully; however, this was the last 'go' at romanticism. Everyone sensed it, and so it was taken to an extreme where the romanticism was perverted and turned into grotesque monstrosity.
However, not everyone embraced this extremity. And I think it would be a mistake to totally disregard every German soldier's sacrifice based on the terrible behavior of some individuals and their fanatical leaders....
