My insight is more about the writing than his actual role in any story. I think Aatrox's dialogue is frankly brilliant satire.
Think about it, what has been some of the most common complaints about the lore and the new characters over the last few months?
-The lore keeps trying to overpower themselves, everything is all powerful gods and otherworldly creatures.
-Varus's lore rewrite is idiotic. Also his name doesn't even follow the Darkin name convention, he needs two As!
-Targon lore is terrible, Zoe is the worst.
-I hate these fuzzy happy childish characters. They're so annoying, I want LoL to be more mature.
-Kayn is dumb, he's just what some kid would design to try and be edgy, but he's really not.
Am I missing any other common one?
And so then they release Aatrox and he goes over all of these. He insults Varus for being two guys and calls it an idiotic plan. He makes fun of the silly heroes and calls them useless and gloats when they get killed. He despises the Targonians, especially Zoe. He loves murdering all the gods and overpowered beings. He mocks Kayn for being an "I'm so edgy" child.
And what is he? He's an a narcissistic screaming manchild that hates everything and just wants to tear down the entire world that the Riot writers have created.
That's us. That's who he is. If this was intentional, Riot kudos your satirical skills are fantastic. I kind of love it.
