[It just seemed wrong. Aang had found a way to stop Firelord Ozai without killing him, and brought the hundread years war to an end. Couldn't they find a way to do the same here, a way that didn't involve taking the life of another being.]

Death is a part of the cylce of life, and there's balance. But taking the life of someone else, it doesn't seem right. There has to be a better way.

You should have to get your hands dirty either, or have to live the burden of doing something so awful either.
