He who joyfully marches to music rank and file, has already
earned my contempt. He has been given a large brain by mistake,
since for him the spinal cord would surely suffice. This disgrace
to civilization should be done away with at once. Heroism at
command, how violently I hate all this, how despicable and ignoble
war is; I would rather be torn to shreds than be a part of so base
an action. It is my conviction that killing under the cloak of war
is nothing but an act of murder.

— Albert Einstein
