Kratos vs Asura was blatant bias. Plus they never had anything in common.
>Kratos was a manchild that got mad that an obviously bad deal he made, went south
>in his rage, he killed most of the Greek pantheon and countless innocents
>Later, he let go of his anger and mostly mellowed out
>Asura was a good guy from the start
>Found out his fellow gods were fucking with shit and then fucked him over
>No matter how angry he got, his WRATH, which is directed rage, never blinded him and he was always thinking about helping people and trying to fix things
>Kills the creator of his universe to do it
