Euthyphro is overconfidence about his knowledge,so Socrates seeks knowledge from Euthyphro since he is facing charges of impiety, thinking he may learn to defend himself in his own trail. he then expresses his thought on how the gods are cruel and inconsistency, which lead him to ask Euthyphro to define "piety" (moral correctness or truth). but with every definition he find a flaw which leads to Socrates not learning anything that will help him defend himself in his trial.
