A properly balanced story provides an equal representation of the negative and positive attributes of, I could say the world, but it's actually a being. 'Harry Potter''s a good example. So Harry's the hero, right. But he's tainted with evil. There's a dark and a light in every bit of that narrative. It's well balanced.
To me, ideology is corrupt; it's a parasite on religious structures. To be an ideologue is to have all of the terrible things that are associated with religious certainty and none of the utility. If you're an ideologue, you believe everything that you think. If you're religious, there's a mystery left there.
