Sasuke is the 2nd Lelouch, but with slight differences. He is becoming a 2nd Obito too. Obito tried to accomplish and fill the hole in his heart all by himself and in the end he failed. Now I see why Itachi was so right when I said "You cannot do things all by yourself, in the end you will lose". But nevertheless what I liked is the great development of Sasuke. He isn't evil and is able to understand things better. Just like Obito shouldered everything by himself, he started a war and united the 5 Villages, now what Sasuke is doing is perfecting Obito's "method". I loved seeing Obito in Naruto's flashback, this makes me think Naruto appreciates Obito as much as Minato. The highlight of this chapter was Sasuke's speech "Naruto's my best friend". Basically, to sum it up Sasuke wants to get rid of Naruto to completely cut the past, rather the feelings of the old Sasuke. It's safe to say that the battle will be as epic as Obito vs Kakashi in the anime since they both started in flashbacks.
I love where the manga is going. 5/5
