Just because everyone knows what you want to say, doesn't mean you shouldn't say it anyways.
We all saw it coming even if we didn't want it to go like that. Sasuke's indecision on whether or not to take revenge lies on the question: Is Konoha worthy of Itachi's sacrifice?
That's where Hashirama and the Hokages come in, Hashirama (together with Madara) were the first ones to develop the concept of Hidden villages, the start of a world where every Shinobi must be ready to sacrifice everything for the village, where morals and principles are bent to the village's will.
Why do Shinobi exist? What is their purpose? What is the purpose of the village?
He learnt then that Shinobi endure all that pain so that others won't need to: Hashirama and Madara created Konoha so that children could grow being children, not warriors.
Tobirama had to change who he was to not be as soft as Hashirama, or as dangerous as Madara, to become the Hokage that Konoha needed.
Hiruzen sacrificed the Uchiha, because a civil war would've only ended in blood and hatred, it was the safest way.
Minato sealed the Kyuubi inside Naruto sacrificing himself and his son, to protect those who lived in the village and giving Naruto a fighting chance against Akatsuki.
Itachi chose to eliminate the Uchiha because he understood the purpose of the village, of shinobi, he left Sasuke alive because his love for him went beyond that of the village.
Sasuke wanted to know the reason behind all that sacrifice, why would anyone endure so much? He needed to understand before deciding. Sasuke is not a fool, he knows by now that making a decision without true understanding of the situation is stupid. He decided that the reason behind it all was worthy after all.
Basically, we knew this would've happened since we learned about the truth behind the Uchiha massacre.
I liked the chapter.
