Thanks Guys for your feedback. I read most of the replies, and there was a recurrent pattern in most of the answers - that is most people are either offended because they think I am degrading Sasuke's intellect, or they think I am trolling. Yet, this question was legit, and I actually meant it when I said I learned nice things from watching Pain arc again.
See, in the Narutoverse, there are ninjas (soldier) who form the shinobi world (all the armies in the verse). There are also civilians who do not even know what being a ninja is. There are actors just like in Hollywood, merchants, politicians, etc. In case you have not notice, the Daimyo or fire Lord is far from being a shinobi, and the Hokage is not a mere ninja.
In fact, I remember when Iruka was talking about Hiruzen. He sure said that Hiruzen had mastered the way of the Shinobi, but he also mentioned that Hiruzen has mastered virtue, the meaning of familly, a village, etc. Itachi also reiterated the meaning of being Hokage, and it clearly shown that being Hokage did not necessarily mean to be the strongest of everybody.
Now, coming back to my initial question, I am pretty sure that you guys have too much hope for the stone tablet. Since the stone tablet was introduced, it has alony talked about the Shringan, Rikudo, the god tree, etc.I am pretty sure that the stone tablet contain zero intel on everything that happened after Rikudo's death. Besides, the stone tablet has been proven to be rusbish written by both Hagoromo (his ignorance of the truth of Kaguya and BZ) and BZ (his lies to trick the Uchihas).
This being said, I think the reason the Uchihas are one dimensional soldier is due to their ignorance of the reality of society, contemporary reality, and the world around them. They are merely soldiers with zero knowledge of human social behavior, and therefore, they spend their life talking about their power, how they will dominate, etc. For example, I feel like Sasuke want to change the Shinobi world based on stupid idea he read from the stone tablet, not from what he learned from the life around him.
Finally, to all the stupid kids who are saying my thread is stupid, you are so ignorant of Sasuke's character that you forget that the only valudable knowledge Sasuke has on the meaning of Shinobi, a village, or love is from the edo Kages. See, until Sasuke met with the edo Kages, he was ignorant of the world around him, and he is so ignorant and stupid that he think he can change such world with the little knowledge he has.
Well, I gave you more details of my so called stupid thread. I will make another thread about the Rinnegan with Jiraya's view of it. Then, you guys will know that Jiraya actually knew a lot of good thing about the shinobi world compared to the stupid and foolish Uchiha clan ( thanks to Itachi Uchiha for these words).
