“All the gentlemen of the world know that they should condemn these things, calling them unrighteous. But when it comes to the great unrighteousness of attacking states, they do not know that they should condemn it. On the contrary, they applaud it, calling it righteous.”
Book 5: Condemnation of Offensive War I
Mozi
Context: The murder of one person is called unrighteous and incurs one death penalty. Following this argument, the murder of ten persons will be ten times as unrighteous and there should be ten death penalties; the murder of a hundred persons will be a hundred times as unrighteous and there should be a hundred death penalties. All the gentlemen of the world know that they should condemn these things, calling them unrighteous. But when it comes to the great unrighteousness of attacking states, they do not know that they should condemn it. On the contrary, they applaud it, calling it righteous.

I, 8
The City of God (early 400s)
Context: To the divine providence it has seemed good to prepare in the world to come for the righteous good things, which the unrighteous shall not enjoy; and for the wicked evil things, by which the good shall not be tormented. But as for the good things of this life, and its ills, God has willed that these should be common to both; that we might not too eagerly covet the things which wicked men are seen equally to enjoy, nor shrink with an unseemly fear from the ills which even good men often suffer.
There is, too, a very great difference in the purpose served both by those events which we call adverse and those called prosperous. For the good man is neither uplifted with the good things of time, nor broken by its ills; but the wicked man, because he is corrupted by this world’s happiness, feels himself punished by its unhappiness.
