wise and just?

The Greeks believe that their “gods and goddesses” are wise and just. That is why they implemented the 4 cardinal virtues because they believe that their gods and goddesses are wise and just,  and they wanted to be like their gods. But in the book of Iliad I saw that these Greek gods are just like bias!! For example Zeus warns the other gods that the war had carried on for far too long and that he planned to bring it to an end. He also warns other gods not to take sides with either of the Trojans or the Achaeans. That came from the mouth of Zeus himself but Zeus who is watching the fight decided to give  the day to the Trojans. Well I think that is not right? Is this book says that gods don’t fulfill their promises? A good question to ask. On the other hand, Hera who was the enemy of the Trojans, ask Poseidon to help the Achaeans but he refuses because of the superior strength of his brother Zeus. In that case, Poseidon don’t want to join a fight because he is just or because Zeus is powerful? For me, Poseidon possesses justice and he is able to do what was right. He can control himself unlike other gods. The gods in the book were not that wise. How can I say this? Because if they are wise enough then they would follow the rules of Zeus, which the superior of them all. Even  though they wanted to help either the Trojans or the Achaeans, then they will not help. That’s my stand. In terms that Greek gods are just, for me they are not just. Why? Because they have their own sides, Example a Greek citizen of Achaeans try to pray to Zeus. Because Zeus is with the Trojans, and Achaeans are his enemies, then he will not answer his/her prayers. In Greeks, if you pray to a god and the god did not respond to his/her prayers means that he/she is not ready to get the blessing or something is missing. Let us say that that citizen of Achaean is doing every thing just to answer his prayer. Would Zeus answer his prayer? Maybe, no because he is an enemy of Trojans. Is that what you call a just god?

For me justice means equality. No bias at all. And that proves to me that the gods are not that just as I expected. That’s all.
