Author's Note: Because there is no way Sora is that bloody cheerful and oblivious ALL THE TIME. .
Mostly my own musings slapped onto Sora, who's a good person to muse them.
Disclaimer: Do not own, blah blah blah.
It's a hopeless crusade, and he knows it. Every enemy he fells goes back to the darkness, ready to spawn a new legion of creeping, crawling soldiers who are so much worse because they can't be reasoned with. Every heart he frees from glowing eyes and snapping teeth goes to Kingdom Hearts, but what's so great about that? None of them know what it's for; all he knows is that it's raw power and that he's had to dispatch two madmen trying to use it for their own purposes. He was sure, once upon a time, that it was light – but what is light, really? He's a warrior of light, but Riku uses the darkness – and Riku is not evil, not sin. Xemnas and Organization XIII were not dark, they were nothing, but they did evil things and released it on the worlds. Roxas certainly wasn't dark, not if he's a part of him… and yet all he's ever heard is that darkness is evil, the Organization was bad, and that Nobodies don't have the right to exist.
What's so bad about wanting a heart? The ends may not justify the means, but he knows that if he could have, he would have given them their hearts back. He thinks of Axel, of the way he betrayed the Organization in a vain attempt to get Roxas back, and he wonders. What is good and what is evil? What is light and what is darkness?
It's at times like this when the Keyblade shimmers in his hand, though he didn't call it, and blue eyes stare the end of it. There's blood there, though you'd never know it. He (and Roxas, because he's him, too) have done things great and terrible, and yet he is hailed as a hero. A hero.
Sora calls out Oblivion, lets his fingers trace the dark metal, and he wonders what his real purpose is. He knows there are things that are left unsaid; he knows he's not a hero, at least not to everyone.
