War  

"It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets" --Voltaire [...]

"War is the continuation of politics by other means" --Carl von Clausewitz in On War (1832)

"The putrid flesh, like the flesh of fishes, gleamed greenish-white through the rents in the uniform. I turned away and then started back in horror: close to me a figure cowered beside a tree. It wore the shining straps and belt of the French, and high upon its back there was still the loaded pack, crowned with a round cooking utensil. Empty eye-sockets and the few wisps of hair on the black and weathered skull told me that this was no living man." --Storm of Steel (1920) by Ernst Jünger
