Well, in honest correction, there might be a few holes in your perception of what life really was like for German citizens during the war. They knew what was going on. Just like we know. To an extent, they knew more than we did. I'd fully wager the common german man and woman knew the most about WW2 than anyone else in other nations involved in the conflict.

When you start your statement with "the bad guy" be sure to understand there was no "good guy".
