When working on a historical project of 20th century (incl. Nazi rule) often I have to do with the question: Should be the focus of interpretation my own view as knowing what happened or should be the focus the acting of people at that time? Don't give the answer BOTH, because even if you consider both aspects - that is the normal case - than you should have a ranking in your interpretation pattern. You have to answer the base question in your own responsibility resp. self-awareness: What comes first?
