Answer and Explanation:
Paul begins to see the war as something horrible, destructive and disturbing. He realizes that there is nothing patriotic about it, nothing beautiful and admirable and that war is a terrorizing situation, long and that does not promote anything good for anyone. However, the German-master continues to refer to the war as something patriotic, which promotes courage and builds the soldier's spirit. This is what causes the conflict between the two characters, because this attitude of the German-master in relation to the war, makes Paul feel repulsion for him.
