Synopsis
Nagato completes his story and asks Naruto for his answer. Naruto agreed on some points, but rejected the overall conclusion on the grounds that it differed from Jiraiya's ideals. To break the cycle of hatred, Naruto told Nagato and Konan that, despite hating them, he would not kill them. Amazed by Naruto's determination to his answer, Nagato says that he would believe in Naruto, and performs the Outer Path: Samsara of Heavenly Life Technique.
