Chapter 13: What conclusion did Bruno come to based on the incident that happened between Kotler and Pavel? Why is this an important analysis of most of German society under Nazi rule

Bruno came to the conclusion, along with the majority of the population, that it was better to avert his eyes and say nothing..... to pretend that nothing was amiss.

And while Bruno realized that Father was generally a very kind and thoughtful man, it hardly seemed fair or right that no one had stopped Lieutenant Kotler getting so angry at Pavel, and if that was the kind of thing that went on at Out-With then he'd better not disagree with anyone any more about anything; in fact he would do well to keep his mouth shut and cause no chaos at all. Some people might not like it.
