2. But I have grown beyond mortals in infinite pain. From mortal to god.
You should prove that you are a big country. However, you will always be the protagonists of this world. Being far away from killing is actually just a mediocre person who pursues peace. Kill or be killed. Connect these two things. War is accompanied by death, scars and pain.
4. Feel the pain, experience the pain, accept the pain and understand the pain. He who doesn't know pain doesn't know what peace is.
Everything makes us awake: human beings are stupid creatures and can't understand each other anyway.
Extended data
In the animation, due to Nagato's mobility, Payne was created to replace all his movements. The subject is Nagato's close friend Yahiko, whose ability comes from Nagato, and he has no self-awareness.
Nagato experienced two great pains in his life, the death of his parents and the death of Yahiko. He was puzzled by "Madara (Uchiha Obito) Uchihiro" and decided to cultivate peace in a painful cycle.
In the event of destroying Konoha, he was influenced by Naruto Uzumaki and regained his boyhood dream. Later, he used "the art of reincarnation" to resurrect the people who died when Payne attacked Konoha, and entrusted his will to Naruto and died of exhaustion.
