But chakra is what has been causing all this evil and power quests, hasn't it? Chakra only came into the world because Kaguya ate the forbidden fruit, much like Eve releasing sin into the world in the bible. Like sin, however, chakra is often perceived as not necessarily bad, just a part of normal life. I think that the greatest sacrifice Naruto and Sasuke have to make is not a person, but chakra itself, in order to stop evil from spreading and the world being destroyed.

I neglected to say how Kaguya might fall, and the truth is I think Madara will have a part in it. Obito, though now dead, first gave him the sense of the question on whether power was truly everything. Madara, in a deep subconscious, will realize that he was much happier when he was friends with Hashirama, so he will gain enough strength for his consciousness to break through and he will stab himself. Since he contains basically every kind of chakra, a large explosion will occur, resulting in the rebirth of the God-Tree. However, since Naruto still has part of the Nine-Tailed Fox, he must make the decision to abandon his own power and send it back into the fruit. Madara's spirit will then trust Naruto to keep the fruit safe, and make sure nobody eats of it and brings back war.

I'm not really sure if this is how I want Naruto to end, but it does make a lot of sense to me.
