《韩非子·八经》
可见罪名和罪行相符时就该严加处置。留着这些人要坏事，杀掉又会败坏名声，就通过饮食毒死他，否则就交给他的仇敌杀掉他。这叫做除阴奸。蒙蔽也就是诡诈，诡诈也就是变化无常。
生害事，死伤名，则行饮食；不然，而与其仇：此谓除阴奸也。医曰诡，诡曰易。
It can be seen that when guilt and crimes match, they should be dealt with severely. Keeping these people will lead to bad things. Killing him will damage his reputation. Poison him by food or hand him over to his enemies to kill him. This is called eliminating evil. Deceit means cunning, and cunning means capriciousness.
