Well,I am impressed!However,I would like to point out a few things about Greek history and mythology
if anything is mentionned before,forgive me for repeating it)
-In Iliad and in Greek mythology,in general,there is no typical evill vs good in the way Tolkein describes it.In fact,even in "Kosmogoneia",none of the gods,even Uranus, is perfect.In fact,the point of mythology is to point out the value of ballance,of divine order,that when it is broken(ύβρις),it makes the one who did it an awful sinner,even if he didn't mean to do anything bad.So,that is the reason why there is a balance of good and evil characters in Iliad(ex.Nestor )
-No hero has only one dimention.Achilles was not as cruel as they say.He looks pretty much like the true Medieval knights.Rutheless at fist,when Priam visits him so as to request Hector's body,Despite his hard attitude,inside him Achilles breaks and gives it at last to Priam.Aso,he didn't permit Patroclu to take his place easily,but after one year of watching his people being slayed bue to his not so weird anger(former disputes with Agamemnon are implied)
Neither Clytemnystra is just a mother avenging her daudhter's/niece's death.She had a young lover and Agamemnon's relative,Aegistus,and seeked to rule Mycenae by herself by using her wak lover as apuppet(Sauron-Saruman parallel,perhaps)
-Αgamemnon hasn't killed his daughter.Firstly,according to the myth,A rtemis took her and placed a deer in her place.Secondly,Ifigeneia's true parents were Helen and Theseus.
-Concerning Odesseus,there is an amazing tragedy,"Filoktitis",that shows what he really represents;the inventing and clever merchant and mariner,the enemy of the traditionnal farmer-lords,as the rest of the kings,the warriors and the Trojans.
-As for the question whether the Greeeks or the Romans were the worst,Ivote for Romans;yes,we made great slayers and civil wars too,but they took all massacres to a much higher level.
