Hatake Kakashi — memorable quote from Naruto

“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!”

“I'll admit that you're stronger than before. But because of that, you seem to have lost sight of what's truly important. Now listen carefully. The people of the village, who once abhorred you, have begun to admire you. They think of you as a comrade. It's because you fought hard for their acceptance. You once said it was everyone who cares about you who helped you get where you are now. If you forget others because you have power, and become arrogant and egotistical, you'll eventually become just like Madara. No matter how powerful you become, do not try to shoulder everything alone. Becoming the Hokage doesn't mean people will acknowledge you. But when the people acknowledge you, you can become Hokage. Never forget your friends!”

“Trying to improve by learning from others that is what calls friendship.”

“There's is no such thing as a useless player.”

“I know we can't immediately treat her as part of our group, but if we always think of her as an outsider, she'll never have a chance to become part of our group.”
