New Aatrox lore vs voice overs

It's not fair to the rest of the world for Aatrox to achieve oblivion but you can see why he wants too destroy everything when he is faced with years(cant remember) of sensory deprivation and solitude. But ingame he basically says "AAAHHHHH I'M EVIL AND I WANT TO KILL!" in most of his lines. I think his ingame character is shallow for something that has lived a massively long time.
