People with high spirituality are easy to enlighten, but hard to control. People with strong animalistic nature are too savage, and also hard to control. Only human nature has a fatal weakness—it's extremely easy to domesticate. Given this, the system's game should be designed this way: First, use religion to suppress your rationality. Second, use morality and law to suppress your animalistic nature. Third, domesticate your humanity, making you completely lose yourself. The goal is systemic stability and order.
