It is true for Bruno, because he 's pretending to be a jew to go with Shmuel. But no body ever told him anything about it, so he really doeesnt know any better. His father wears tht uniform and thinks he 's "all that", and he know 's what he 's doing, and that "it 's for the greater good" (even though it is possibly one of the worst things to happen in history, so i guess its true for him too). All throughout the book people dress up and try to be that person, pretending to be someone else. But they really are all making the wrong choices, the wrong desicisons, but they have no-idea what they are doing is going to scare our world
