Itachi in “Unfinished Business”

Itachi

[To Naruto] I admit you are stronger than before. You have much more power but as a result you seem to have lost sight of something extremely important. Naruto, you must remember. You know why the people of the Leaf Village stopped hating and fearing you. You know why they've accepted you as one of their own. It's because you showed that you understood them and you fought for their acceptance. You just said everyone who cares about you helped you get where you are. If you forget about everyone else because you now have power, you'll become arrogant and egotistical and eventually you will become just like Madara. However powerful you are, don't take it all on yourself, because if you do you will surely fail.
