Three plots in the story best reflect the good and evil of human nature: one is that Norman, who has just entered the war, has suffered several casualties among his teammates because he can't bear to shoot at young female Germans, in order to exercise Norman, Captain Don let him shoot the German prisoners, but Norman is delayed; the other is that when Don and Norman break into a German family, Norman plays the piano in the master's room, the German girls sing beautiful songs with the music, they fall in love, but soon the German girls are killed; finally, Norman hides under the tank. A German soldier shone a flashlight on him, but he only glanced at him, did not shoot, but quietly walked away.
