Here's why:
* Ignorance and apathy: They are aware of the "farm" Bruno's father manages, but they are deliberately ignorant of its true nature. They choose to ignore the horrific reality of the concentration camp.
* Blind obedience: They are unquestioning of the Nazi regime and blindly follow orders, even if they are morally wrong. Ralf, in particular, justifies his actions by saying he's just following orders.
* Complacency: They live a comfortable life in the midst of a horrifying atrocity, showing little concern for the suffering of others.
While Bruno's mother shows some empathy and tries to understand what's happening, she's ultimately powerless to change the situation.
Other examples of naive adults include:
* The camp guards: Some are simply following orders, while others may genuinely believe in the Nazi ideology. Their naivete lies in their inability to see the humanity of the prisoners and treat them with respect.
* The German society: Many people in Germany during this period were complicit in the Nazi regime, either through silence or active support. They were naive in their belief that the Nazis were justified in their actions.
It's important to note that naivete doesn't excuse their actions. It's a complex issue, and the film highlights how easy it can be to fall into ignorance and complicity. The adults in the film represent the dangers of blind obedience, apathy, and the normalization of atrocities.
