He's not really meant to be likable... at all. He's an anti-hero.
Nothing he does is for any greater cause, or for someone else, but his twisted desire for vengeance due to the actions of a single god, which then sends him into realms of madness, which leads to further betrayal from other gods, which in turn leads to more violence.The fact that you hate him is actually a part of the desired end result. You're simply following the characters descent into the darkness of his thirst for blood.
If you want a proper, heroic and likable main character, then your looking in completely the wrong direction with God of War. Personally I like the whole anti-hero concept because it's a nice change from the "proper" heroes of most other games.
