This film does a tremendous job of displaying the fact that "evil is evil", whenever and wherever it is, you can see it by the fruit that it bears. From the gulags of the Soviet Union, the mass slaughters perpetrated by communist dictators to seize control, or the fanatical frenzy caused by the leaders of Fundamentalist Islam this very hour, evil can be spotted by the results it yields.
And while none of us are perfect, and all of us have done bad things in our lives, there is a whole other level when it comes to the truly evil things that have been perpetrated by people who seek to solve all the world's problems through government control. The Communists did it through forcing strict adherence and allegiance to "the good of the state", and if you didn't comply, "Here, hold this bullet for me... in your head". And the leaders of Fundamentalist Islam today do it through forcing strict adherence to a set of guidelines set forth by their holy book, and if you don't comply (or try to convert to another religion), "Here, hold this bullet for me... in your head".
