Yeah, you don't know.I know exactly what happened in that entire ordeal. Itachi hid the genjutsu inside Naruto to use on Sasuke but it ended up being used on Itachi instead. Just because it was Itachi's jutsu doesn't take credibility away from Naruto. Itachi was completely under Kabuto's control until Naruto came along. Naruto's heroic, hokage-worthy behavior is what convinced Itachi to trust Naruto with such a power in the first place.
Itachi used the Genjutsu on himself, it had nothing to do with Naruto at all.
He was always under Kabuto's control until he used the Genjutsu to free himself, Naruto did nothing.
What heroics?
