Euthyphro Continued

Can I just say that after reading the text one more time, the discussion between Socrates and Euthyphro seems almost useless. Socrates knows what he wants Euthyphro to say, he even admits it. So why not just save some time (and Euthyphro the energy) and explain his theory on piety?
I understand that Socrates wants Euthyphro to teach him so that Socrates gets out of his little indictment (which seems like it is a common occurrence). Anyways, onto how a I think Euthyphro answers Socrates never-ending question.
First, Euthyphro compares piety to righting the wrongs of a society. In this context, it really makes sense since they are both going to trial for something. But who says that it was Euthyphro's job to make the society the perfect place to live? What if it only makes the society the perfect place for him? I think Euthyphro is very bias when he gives his first example/definition of piety.
The society in which Socrates and Euthyphro live clearly does not separate church and state like the more modern countries of today. The remaining three definitions all involve abstract ideas that are impossible to sum up in one sentence, let alone in the presence of a great mind like Socrates.
After failing miserably at his first attempt, Euthyphro makes his job even harder by defining pious using undefinable things like love and gratification. Poor Euthyphro.... he looks even dumber the longer he talks (he looks stupid to begin with I think...he's persecuting his father!)
