Yeah. When the Samurai realize the truth of what he says and all immediately become downcast with shame, realizing what they as professional warriors have done to the people, it's such a powerful moment. I interpret it as a commentary on the Imperial Japan period, and how the expansionist warmongering of that era lead to the utter destruction of the Japanese mainland and the death of millions.

And I really like that; The Samurai don't save the town. They teach the people to fight and lead them. Vanguardism for the win!
