One reason, of course, was that the Nazis were lying to each other even before they were lying to the public. But then isn't that the nature of evil? Lies within lies within lies. Lies to hide the the lies about what you're hiding. They developed an intense dogma of Rationalization of what is necessary or what is "good," what it means to be human, which was fueled and kept together by the two elemental weapons of evil: fear and lies.
The Nazis give us one of the most excellent examples of the strangling web of evil than can only end in the way Hitler almost poetically obliged us all: suicide.
But just because most of us aren't Nazis, it doesn't mean we're any less capable of sliding down that same icy slope of despair and fear. That privation, that emptiness of goodness we call evil is like a quarter you drop between the seats in your car that you quickly resign to retrieve some other time. If you treat your lies like small change, pretty soon, you'll end up with a purse full of ...."treasures" that make more than your shoulder hurt.
