Fate/Zero (2010)

There’s no hope on the battlefield. It has nothing but unspeakable despair. Just a crime we call victory, paid for by the pain of the defeated. Yet humanity has never recognized this truth. And the reason for that is, in every era, a dazzling hero has blinded people with their legends and prevented them from seeing the evil of bloodshed. The true nature of humanity has not advanced a step beyond the Stone Age.

Knights cannot save the world. They call certain methods of fighting good and others evil, acting as if there were some nobility to the battlefield. Such illusions, perpetrated by heroes throughout history, have led countless young men to their bloody deaths, all for the sake of this valor and glory.
