Algren: What do you want?
Katsumoto: To know my enemy.
Algren: I've seen what you do to your enemies.
Katsumoto: The warriors in your country do not kill?
Algren: They don't cut the heads off defeated, kneeling men.
Katsumoto: General Hasegawa asked me to help him end his life. A samurai cannot stand the shame of defeat. I was honored to cut off his head.
