Correcting errors is not difficult.
But in today's world, correcting errors has become increasingly difficult.
Why?
When it's possible to gain endless benefits from errors, who would care about right or wrong?
Thus, the eventual downfall of ancient rulers seems incredible in hindsight, but when certain people are in those rulers' positions, they do things much the same, if not even worse.
It's not just errors that are difficult to correct, but also increasingly obsessive desires.
Desire is not without reason, because humans in the Desire Realm naturally move forward with desires, but whether to restrain desires while moving forward or be a puppet of desires and sink, is something humans can choose.
