Euthyphro is motivated by to hosion (the holy) to prosecute his father (the prosecution will remove the pollution of murder). Socrates has contrived a portrayal of the gods whereby they are in conflict with each other primarily because they disagree who among them acts justly or unjustly in any given action. This nonsensical portrayal is based on opinions held by Euthyphro, which is why Euthyphro agrees with it. Socrates finally begins to bring this new emphasis on the problematic nature of justice to bear on Euthyphro's prosecution of his father.
