Fate/Zero #19. “正義の在処”
(Seigi no Arika)
Where Justice is Found -sometime, somewhere-
"Emiya Kiritsugu, I don’t know what betrayed you and caused you to fall into such despair in the past. But your rage and sorrow are found only in those who once sought justice. Kiritsugu, in youth, deep down, you must have wanted to become a hero. You believed in a hero to save the world. You desired it more than anyone."
