The hero had worked like an ox for the gods, diligently and conscientiously, for twenty-five years. He saved the world, then was reborn.
At the moment of his rebirth, the hero finally saw the light.
Justice? Humility? Compassion? Kindness? Glory? The hero's noble virtues?
What a load of crap. I'm done!
Why fight one-on-one when we can gang up on them? Why not use poison? How dare you refuse a righteous sneak attack? If groveling to the elemental spirits gives me power, I'll grind my forehead through their magic circle. If the church annoys me, I'll kick its robes apart at the seams, and it won't dare say a word!
Getting rich off my hero status is part of the story too. If you don't like it, don't play.
