Every dynasty had its day of reckoning. The only difference was a matter of time.
Royal power changed hands again and again, but it was always the common people at the bottom who suffered.
Amegakure perfectly embodied this principle. From a historical perspective, because of its unique geographical location, Amegakure was often treated by the Five Great Nations as their default battlefield.
After all, no one wanted war to break out on their own land. It would be an enormous test of their local economy and stability. Thus, the Five Great Nations tacitly chose a universally acknowledged unlucky victim: Amegakure.
The wars between the Five Great Nations had their winners and losers, but Amegakure, at the center of every conflict, had never won. It was either being beaten or on its way to being beaten. Chaos and flames of war became the dominant colors here. Without a true Kage-level powerhouse, Amegakure could only silently endure this fate.
But things changed after Hanzo emerged. This man, known as the Demigod, showed an exceptionally hardline attitude toward the outside world after taking power through forceful means. That era belonged to Hanzo. He faced the future Konoha's Three Sannin alone without falling behind in the slightest. In fact, Jiraiya and the others only survived because Hanzo had shown mercy.
Of course, that was also related to Jiraiya and the others being too young at the time and lacking much combat experience. Even so, it was enough to show just how formidable Hanzo had been.
Unfortunately, the older Hanzo grew, the stronger his thirst for power became. That very thirst gradually twisted him and eventually became the root cause of his death.
In short, after all that, Hanzo had long forgotten his original aspirations. Great strength brought great power, and profit blinded the eyes.
