And why we could die when the others couldn't. And why so many of us did die. And, well, this may be the last chance I get to ask this, since, even if I don't want to kill you, a lot of people do and I can't stop them."

He did want the people they lost back. But Aang had spent years learning that people die and there was nothing he could do about it.
