"People are stupid. If I don't do this, there will be no peace. Eventually, time will pass and the pain will heal. Eventually, checkmate's power will weaken and people will begin fighting again. This time, they will use the weapon themselves and once more know true pain. And for the short time, peace will come again. It will give birth to short period of peace within this endless chain of hatred. That's my wish."

"Up until now, my bonds with others have only been ones of hatred and murder. But, seeing him fight so hard made me wonder what a bond really is. I think I understand a little now. Suffering, sadness...and joy. To be able to share it with another person. Naruto Uzumaki...when I fought him, I feel that is what he taught me."

"You're gonna fight Sasuke alone? And you think all of us are just gonna stand here and let you?!"

"You are the strongest enemy I have ever fought."

"Sharks start out as eggs, but incubate and hatch in the womb. Sometimes the number of pups is less than the number of eggs that were fertilized. Do you know why? Cannibalism. The pups start eating each other within the mother's womb the moment they hatch. They start killing their siblings the moment they enter the world, viewing everything they see as nothing more than prey. As of today you and I are fellow members of Akatsuki. So be careful... of me."

"Three times now... We've fought world wars for our own nations, our own villages. We've hurt one another. We've hated one another. That hatred bred a lust for power, and that lust for power created ME. I was a Jinchuuriki, the embodiment of hatred and power. And I hated this world, and all the people in it... I wanted to destroy it with my own hands. The exact same thing Akatsuki is trying to do today. But one man, one ninja from Konoha stopped me. I was his enemy, yet he wept for me! I hurt him, yet he called me his friend! He saved me! My enemy, my fellow Jinchuuriki... He suffered the same pain as me, yet bore no ill will! There are no enemies here because we've all suffered at Akatsuki's hand! SO THERE IS NO SAND, NO STONE, NO LEAF, NO MIST, NO CLOUD! THERE ARE ONLY SHINOBI! And if you still hold a grudge against the Sand, then when this war is over, come and take my head instead! Our enemies are after the friend who saved my life! If they take him, if we hand him over, our world is finished! I want to protect him, and I want to protect our world! But I'm too young to protect it all on my own! All of you lend me your aid!"

"Grow up... Death comes with being a shinobi. There are times when death is hard to accept, but if you don't get over it, there's no future..."
