Meditations 9.4

He who does wrong does wrong against himself. He who acts unjustly acts unjustly to himself, because he makes himself bad.

Marcus Aurelius, Meditations 9.4, translated by George Long

He that does wrong, does wrong to himself. The unjust man is unjust to himself, for he makes himself bad.
