In fact he did; he also did it by saving Naruto several times.
Can i safely say that Lee saved the world because he saved Naruto from Kimimaro's attack?:O He was going to kill him; and Naruto had a big effect in the war.
Nice find. I noticed that and thought it seemed like Kakashi and Rin but I never thought about how Naruto would react had Sakura died. He could've went mad! Well done
