"Euthyphro: It is ridiculous, Socrates, for you to think that it makes any difference whether the victim is a stranger or a relative. One should only watch whether the killer acted justly or not; if he acted justly, let him go, but if not, one should prosecute, if, that is to say, the killer shares your hearth and table. The pollution is the same if you knowingly keep company with such a man and do not cleanse yourself and him by bringing him to justice. The victim was a dependent of mine, and when we were farming in Naxos he was a servant of ours. He killed one of our household slaves in drunken anger, so my father bound him hand and foot and threw him in a ditch, then sent a man here to inquire from the priest what should be done. During that time he gave no thought or care to the bound man, as being a killer, and it was no matter if he died, which he did. Hunger and cold and his bonds caused his death before the messenger came back from the seer. Both my father and my other relatives are angry that I am prosecuting my father for murder on behalf of a murderer when he hadn’t even killed him, they say, and even if he had, the dead man does not deserve a thought, since he was a killer. For, they say, it is impious for a son to prosecute his father for murder. But their ideas of the divine attitude to piety and impiety are wrong, Socrates."
