This is really interesting, although another huge reason that the citizens of nazi Germany obeyed such orders is the influence of the social acceptable, whose's huge reasons for existence are fear and pride, which were both hugely in that time. And when it comes to soldiers, they were simply "doing their job" of obeying any orders of authority without any reaction or even questioning. So a better way to use such an experiment would be to use more people at the same room, at the same time, some of which we would intensially put there to do as we say, just to do as we want, so we would also see different results influenced by the huge factor of social acceptance. So I see this thought as a personal motivation, to go soon and try this updated experiment on a different way obviously, as a way of research, and film it.
