Although Baretski seems to have registered the horror that he and Lale witnessed in the gas chambers, Lale clearly senses that the man doesn’t feel genuine remorse. Instead, Baretski fails to realize the gravity of the persecution he and his fellow Nazis are committing. In turn, it becomes obvious that Baretski’s capacity for empathy is deeply flawed, as he is able to make a joke not only about the horror he’s just seen, but the way that this horror affects Lale. In doing so, Baretski demonstrates his callousness while simultaneously reminding Lale that Lale himself could someday suffer the same wretched fate as the Jewish prisoners they just saw splayed out in the gas chamber.
