The Trials of Socrates.......

In the first chapter of the Trials of Socrates, Socrates starts a discussion with Euthyphro on what is pious and impious. Euthyphro says that pious is what the God’s love and impious is what is not loved by the Gods. Later in the discussion Socrates questions why should one pursue pious acts just to please the Gods, when if Gods have everything already then there is nothing that you can give them with your acts of goodness or virttue. So my question to you is how should we base our acts if there is nothing we can give God? Aristotle said that each action toward good should be chosen for the good in itself, meaning I choose to act virtuous because virtue is the "good. Any other thoughts on this?
