World War II is the greatest drama in human history, the biggest war ever and a true battle of good and evil. I imagine writers will continue to get stories from it, and readers will continue to love them, for many more years.
You can make yourself feel better about yourself if you project your shadow side, if you project your own potential for evil onto someone else. By annihilating them and, therefore, your shadow, you bring yourself into some state of purity or reformation.
