To defeat an enemy, you must destroy both their Means, and their Will, to resist.
You cannot destroy the peoples will to resist, on the battlefield alone.
I would agree with you if this was done at the beginning or the middle of the war but the 'battlefield' as almost over and the Germans were already beat. I know many historians agree with you but many do not and say this was just vengeance on the part of the allies which I agree with since Germany was already a defeated nation.
