《后汉书·列传·蔡邕列传下》
他对有恩的人，哪能不想念呢！正直无私的人，处决一个罪犯，尚且还吃不下饭，何况国家的刑典，出于仓卒，事前没有想到，以至怜悯变容，哪能按奸邪同罪！
君子断刑，尚或为之不举，况国宪仓卒，虑不先图，矜情变容，而罚同邪党。
How could he not think about the people who were kind to him! A man who is honest and selfless, executing a criminal, still cannot eat, how much less is the state's law, carried out in haste, unforeseen, so that compassion changes expression, and he will not punish a man who is a criminal the same as a man who is evil!
