Naruto - Chapter 401
Ilusion

Sasuke is still trying to deny Madara’s story although, more logically this time. Madara has an explanation for everything. Itachi really planned ahead with killing Orochimaru and making Sasuke able to use the Mangekyo. Itachi completely controlled Sasuke’s perception of the truth.
Itachi’s strange condition has also been explain. He was sick for a long time already.
Things are not so bad. Itachi died with a smile and Sasuke now knows the truth. The problem is his consciousness, since he killed his loving brother.
Sasuke comes out of the hideout and emptily gazes at the sea. He could now come back to Konoha without exposing the lie and be considered an hero, like Itachi wanted. But, I guess will most probably expose the lie and take revenge on Konoha although, that could cause Konoha a lot of problems.
This is what Madara probably wants, he’s still angry at Konoha. Also, this way, Itachi would be considered one of the greatest ninja.

Now, still many mysteries remain. Does Madara intend for Sasuke to cause chaos in Konoha while he collects the Bijuu and creates his great ninja organization? This would weaken Konoha, which must also be one the biggest obstacles for his plans.
I think this was the last chapter on the subject. What will happen now? And how did Madara live so long? What’s his strange jutsu about? What is Pein?
