When Ryu thought of Deterrence, it seemed to perfectly coincide with Temperament. The latter was the overarching umbrella while the former was one of the many tidbits stored within.
Ryu actually felt that for a moment that it was quite a valuable comprehension. In fact, he could probably make a Dao Technique similar to [A God's Brush] if he pursued that path further.
But was it the right path to take?
Dividing Order and Dividing Chaos… It was meant to look at the world from a macro level.
Using Temperament as a means to breakthrough made sense because it was a piece of the puzzle that he hadn't yet considered. But Deterrence was beneath that same umbrella. If he honed in on the details too much, he might miss the forest for the trees and steer his Dao down the wrong path.
Others might end up bottlenecking their Daos and being forced to weaken them to progress because their comprehension was too low.
