Final answer:
The incident where Idek attacks Eliezer in 'Night' emphasizes the constant threat of violence in the concentration camps, contributing to the narrative of unending brutality and the themes of bystanders enabling perpetrators during the Holocaust.
Step-by-step explanation:
In the book Night by Elie Wiesel, the author uses the incident of Idek attacking Eliezer to highlight the ever-present threat of violence within the concentration camps, notably exemplifying how individuals like Eliezer are continuously exposed to unpredictable and unwarranted aggression. This incident helps to advance the plot by establishing a grim tone and illustrating the perilous environment that the prisoners are enduring. The Holocaust serves as a backdrop to this story; the narrative underscores the daily horrors and inhuman conditions that were a part of life in the camps, including random acts of cruelty from figures of authority like Idek.
In the larger context of the narrative, such events are not isolated; they feed into the theme of bystanders enabling the perpetrators. Drawing a parallel with historical accounts, it's evidenced that the systematic mistreatment and ultimate genocide of the Jews and other groups deemed 'inferior' by the Nazi regime was not only done by the hands of the perpetrators but also through the inaction of bystanders. The attack by Idek thus serves as an example of the cruelty faced regularly and the oppressive atmosphere that never allowed the prisoners to feel safe, reinforcing the narrative of the senseless brutality that defined the expanse of the concentration camps.
