Final answer:
Hans could get on the “bad side” of the Nazis by not conforming to Nazi ideologies, participating in or supporting resistance efforts, or simply not actively participating in Nazi crimes, leading to being labeled as subversive or disloyal.
Step-by-step explanation:
Hans could get on the “bad side” of the Nazis through various actions that defied the party line or resisted their policies. During the rise of Nazism in Germany, individuals found themselves as victims, perpetrators, or bystanders. Primo Levi's perspective on the danger of “common men” aligns with the idea that those who either passively or actively disobeyed or did not conform to Nazi ideologies could be viewed negatively by the regime.
Martin Niemöller, a vocal opponent of Adolf Hitler, depicted the peril of collective inaction through his poem. By speaking out or by simply not participating in the Nazis' crimes, such as the Einsatzgruppen's “Sonderaktionen” (special action), one could become viewed as disloyal or subversive by the Nazis. Similarly, in World War II, partisans who resisted the German occupation and activities, including guerrilla warfare, would certainly be seen as enemies by the Nazis.
Furthermore, individuals or groups that did not align with the Nazi's racial hierarchy, criticized their treatment of so-called “enemies” like the Jews, or objected to the injustices stemming from laws such as the Nuremberg Laws, could quickly find themselves targeted by the regime. These acts could be anything from passive resistance to active participation in efforts against the Nazis, such as sabotage, helping victims escape, or disseminating information contrary to Nazi propaganda.
