Yes, I agree. I also think teachers should also go over the process of how people think and why they do what they do, no matter if the person knew their motives or not. History, also repeats itself because people doesn't realize how the same philosophies are eventually leading to the same type of downfall and doom. Such as Marx's Marxism in the United Socialist Soviet Republic or Plato, Kant and Heggel's philosophical in Nazi Germany.
