Blackout Done in Sepia
There were few people Gaara, setting out in order to execute his mission to destroy the Leaf country, hated. Most people he ignored with the sublime indifference of a hawk to an ant, only dimly aware of the fact that he could easily destroy any of them, if he chose to.
Sometimes the ants spoke to him, stayed at his house, made demands in the name of shared blood, but it was all seen from a vast distance, with no real emotion attached.
The first person he hated, truly hated with the fire and blood of a frustrated child, was Lee. He hated him because he had Gai, and because there were two others as well who stood by him and lifted him up when he could not walk. He hated him for being his opposite, a hardworking talentless loved by those closest to him.
He hated him because he dragged Gaara down to his level, and demanded respect and attention.
He dealt with Lee with violence, and swore that the day would come when he would kill him, and all his loved ones would gather around and cry until their eyes bled, and then Gaara would remember it was better never to love, and avoid the pain of loss.
Sasuke he did not hate, although he came close to it. Sasuke excited him, as a rat before a dog, and Gaara wished nothing more to sink his teeth into Sasuke's neck, and shake him until his spine snapped. Sasuke was perhaps a falcon – worthy of respect, but still beneath his level in terms of strength.
Sasuke was weaker than him, and thus would eventually be killed by the sandnin. It was inevitable.
Naruto Gaara loathed as he would a broken mirror, forever throwing his face back at him, hideously distorted by the deep-running cracks. He was his own shattered reflection, grinning back at him from a hundred bloodied shards, and even if Gaara ground those shards into dust he knew that the reflections would still be there, mocking him with their presence.
Naruto was Gaara, twisted by affection, and so received all of Gaara's self loathing, compacted into a lethal form.
The last person he hated, hated so hard it almost physically hurt, was Sakura. He hated her because she should have been an ant, just another insect ripe for the crushing, but she had grabbed hold of his feathers, and refused to be silenced.
She had jumped in front of Sasuke, and there had been love and determination burning in her bright green eyes, but it was not the love Lee received, it was something more, something Gaara had never seen before, and it drove him into a frenzy of wrath.
It was something he wanted to posses so badly the only solution seemed to be to destroy it. It was a weakness morphing into strength and it was something Gaara knew would never be a part of him.
Sakura he hated because she loved, and love was the one thing he could not forgive.
