I like the framework. The idea that desire is a universal part of the human condition is a good one. In thinking about the three desires you've listed – possession, deliverance, and revenge – I can't help but wonder where internal desires fit. The listed desires seem external in nature; that is, something outside of the hero's inner world. Where does something like the pursuit of meaning, the hope that you will be remembered, or the desire to feel loved, fit? Those desires seem equally, if not more powerful as drivers of the human condition.
