When Bruno dresses in the filthy pajamas, he remembers something his grandmother has once said. „You wear the right outfit and you feel like the person you're pretending to be. “ (p. 205) How is this true for Bruno?

By the end of the novel, Bruno has a tremendous amount of empathy for his friend Shmuel. His innocence prevents him from understanding, in the last chapters, the fate he is about to experience in the gas chamber. As he is marched along with the other prisoners, "he wanted to whisper to them that everything was all right, that Father was the Commandant, and if this was the kind of thing that he wanted the people to do then it must be all right" (210). Bruno is, of course, completely wrong: this is the sort of thing Father wants the Jews to do, but there is nothing "all right" about it. The very character in whom Bruno has faith is the one who is bringing about the deaths of so many, his own son included.

Exellent body of work but you missed the poit in the question. The question was how is this true for bruno - you wear the right outfit and your the person your pretending to be.
