history
From the Shi Ji biography of Wu Zixu (《史记·伍子胥列传》). After whipping the corpse of the late King Ping of Chu, Wu Zixu defended himself by saying 吾日暮途远,吾故倒行而逆施之 - 'my day is late and my road is long, so I acted contrary to custom.' Originally self-defense for extreme action; now pure condemnation.
