Previous Post Which brings up a question: heredity or environment? Are the people of Earth X naturally evil ala the Star Trek Mirror Universe or is it just that they were raised that way due to the Axis winning the war? Sure there are prisoners and a resistance, but that is a natural thing to see in a tyranny.

The only ways I can accept Nazi Kara are:
1. Earth-X Krypton was massively screwed up even worse than Earth.
2. Massive brainwashing. Red K or something similar.
3. Earth-X Kara's history is largely different with her being shipped to Earth as an infant instead of 12 years old.

Our Kara was 12 and her ethics and moralities were largely formed before coming to Earth. Being on Earth really hasn't changed her much. I really don't think a person can become a Nazi unless the seeds were there during very early development (approx. birth to 5 years old).
