"There's only one thing that can heal the heart... Only one... It's love, Gaara."
"I took the life of the woman I was supposed to call mother in the process of being born... in order to become the world's strongest shinobi... an incarnation of sand was implanted inside of me..."
Even though Gaara considered himself to be born monster, and hated himself for taking the life of his mother. His uncle told him that his mother love was in the sand. but in the end he told him that his mother never loved him. and that's some real messed up shiz to say to a child. Later in war, He met his father, who always viewed him as a threat and a object of war.But in Rasa's last moments he told Gaara that his mother always loved him.
"To them I'm simply an object from the past that they wish will disappear Then why do I exist? Why am I alive? When I thought about this I could find no answer. But as you live you need a purpose otherwise it's the same as being dead, I then came to this conclusion I exist to kill every human besides myself. Fighting only for yourself living while only loving yourself. If you think that everybody else simply exist to allow you to experience that feeling, nothing is better then that world. As long as there are people in this world for me to kill and continue to feel that joy of living my existence will not vanish."
This statement explains itself, Even though Naruto and Gaara lived different lives. They share the pain and suffering from those that hurt them or try to. Loneliness is painful feeling, and it can destroy you mentally. Even though Naruto had a dream, a goal to look forward to. Gaara went down a darker path. He couldn't trust no one, not even his siblings, he could only kill to make him feel alive
"Now there's something I understand a little better. Hate, sadness, even joy. to be able to share it with another person...Naruto Uzumaki from fighting him i learned that. he knew pain like i did and then he taught me that you can change your path. I wish that one day i can be needed by someone. Not as a frightening weapon...But as the sand's Kazekage."
This is the main reason why we love him
"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!"
