I am amused, Socrates, at your making a distinction between one who is a relation and one who is not a relation; for surely the pollution is the same in either case, if you knowingly associate with the murderer when you ought to clear yourself and him by proceeding against him.
Euthyphro is amused that Socrates is making a distinction between a relative and a non-relative in this case he argues that they are the same and the fact that you are associated with the3 murderer is in fact worse and that it is your duty to seek punishment for the murderer as to clear yourself from said act
