How is Bruno changed by the social conflict of the Nazi ideals?

From an early age, Bruno has been brainwashed to believe that the Germans are a superior race whose superiority gives them the right to treat so-called "inferiors" however they like. Bruno witnesses this warped attitude firsthand with the abominable treatment of Pavel, his family's Jewish servant.
When Bruno falls from a tire swing and Pavel comes to his aid, he starts to realize that there's something not quite right about what he's been taught. Through his personal interactions with individual Jews, Bruno is able to reach out, albeit tentatively, to those deemed by the Nazi regime to be his racial inferiors. The fact that Bruno is also able to forge a close friendship with a Jewish boy imprisoned at Auschwitz, Shmuel, is a further indication that Nazi ideas of perpetual conflict between supposedly superior and inferior races are completely false.
