What character serves as an emblem of Nazi inhumanity in the play, The Young Lions?

The German, Christian Diestl, is an athletic, aggressive individual whose instincts to compete and dominate find expression in Nazi ideology. As the German army rolls to early victory, Christian enthusiastically savors the food, the women, and prestige that are the spoils of victory. When the German army retreats later in the war, Christian grows progressively ruthless in saving his own skin. He readily kills enemy troops, civilians, his comrades, and even his friends in order to survive. Shaw skillfully depicts Christian's incremental barbarism as the emblem of Nazi inhumanity.
