I think underneath, every human is capable of being a Nazi (or monster) if you will. If they weren't, we wouldn't have so many laws, rights, religions, and philosophies that offer normative approaches to controlling human behavior.
Human nature is the problem - Nazism, fascism, communism, dictatorships, cruelty, injustice, hate, prejudice, etc, are simply symptomatic of that cause.
Why do people want to reproduce and breed more problems? I say let humanity go extinct. There's no loss, and everything to gain for the world and nature. Ultimately, there is no purpose for the continuation of all this suffering up on each other and upon nature itself.
The more populated the planet gets, the worse things will become. Stop breeding people, enjoy the moment, live out your life, and let the Earth takes it's natural course.
