As a Greek when we were reading the Iliad at school, I personally was on no one's side. War is terrible, it takes out every morality and ethics out the window and people do everything to win at this point. Every major death in the series was sad for me, but Hector's more because he literally just wanted to leave a peaceful life with his wife and child and war took that away from him.
So yeah his character is as important as Achilles and the rest of the characters in Homer's Iliad, who was an excellent writer because he wrote every person with care and importance in his story.
Yeah! It's really funky cause while it focuses more on the Achaeans, you still see glimpses of the lives of the people within Troy. There's a whole book of Hector just visiting his family, of Priam asking Helen about the different Greek kings and having mostly good things to say about them. Punctuating the deaths of trojan soldiers with phrases of how their fathers will mourn or their mothers weep. The whole story is just the tragedy of war and wrath, no matter whose side you're on
