Disclaimer: I do not own avatar: the last airbender.
Aang couldn't believe it. He just couldn't. After all of his time and hard work, the fire lord Ozai defeated him, the avatar. He was numb, almost dead, he could feel it in his soul. He was ashamed. Ashamed that he couldn't protect anyone, ashamed that he lost. Aang knew that he was the only avatar to not complete his mission. He couldn't even make sure that the world had peace and harmony, that simple task. In the back of his mind, he knew that that wasn't simple. But the part of his brain of him that he was listening to told him that if all of the other avatars did, it, why couldn't he?

He wished that Katara was there, she always knew how to comfort him. But he knew that she had been shot down too. He had even seen it happen, seen the evil monster shoot the arrow into her leg. Then shoot another into her arm. He saw Katara helplessly try to dislodge the arrows, without success.
As she slumped down in pain, Aang couldn't control his power, even though he had mastered the avatar state. His pain and fury were enough to make anyone crazy. But since he was the avatar, he had to do something with this anger. As he rose into the air, he vaguely noticed all of the fire directed his way. Aang knew he had fallen then, but without Katara to come to his rescue and catch him.
In the last moment before he hit the ground, Aang knew that he had failed. He could hear his legs break, that horrible gunshot-like noise. But he felt his anger and powers combine more than ever, and unleashed that powerful blast. He had combined all four elements, something he knew that no one had ever done before. He had killed everyone for miles. He knew that the fire lord escaped, when he was falling from fatigue after the bending event, he saw him run off, virtually unharmed. How the fire lord was alive, Aang did not know. All that he knew was that he had failed.
But the only person that he cared that he lost was Katara. She was probably still alive when he let out that horrible blast, knowing that Aang had really killed her. She was dead, and it was her best friends fault.

Aang limped over to her body with most of his remaining energy. "I'm so sorry, Katara. I didn't mean to kill you, to kill everyone. I know you hate me now, but you have to listen." Aang was in the stage of delirium now, thinking that he and Katara were at the Southern Air Temple. He imagined all of the monks around him, angry and hurt. "I don't care that everyone is here and listening. I love you Katara, please just remember that before you leave. You can have Appa when you go, he's mad too. Just know that you are loved, and never forget me, please?" Aang begged the air in front of him.
He heard Katara in his dreams, though she sounded different, distant almost. "Aang, I do not blame you for what happened. I just wish that you had survived. You could have helped so many more people, and stopped the fire lord. But destiny does what is does, and that's what we have to accept. You should know that I will always love yo-..."
"Katara, Katara? No! Don't leave now, We need to talk some more!"
He broke down in seizures then, his life to be taken at any moment. But in the fading light, he saw Katara's body, and died with a smile played across his lips.
