He has been hailed as the prodigy of the uchiha clan,posessed the wisdom of a hokage at age 7 a
yet has the intelligence of a 5 year old at age 21. he made some of the dumbest mistakes in the manga which resulted in catastrophic war and death
He died because he was a good guy
who brutally and sadistically tortured an innocent child, betryed and condemned konhoa to destruction, and murdered 6 jinchurikis, even giving nukes to 10 terrorists
he even has totsuka and yata which can solo all.
yet he was scared of akatsuki and didnt even try to slow them down
Yet even death was not able stop him from totsuka gg nagato,and save the shinobi alliance by stopping edo tensei. O
the alliance was not even remotely threatened by kabuto compared to the threat posed by obito and gedo. kabutos edos for the most part had already been defeated. so they saved themselves.. in fact ending ET when he did condemned the alliance to being mostly massacred, and neji/gai dying.
it was no plot.he work for the village and die giving eyes to sasuke.he wanted to sasuke to get strong and same time hide the truth.
wrong on both counts. he didnt give a shit about konoha and betrayed it for akatsuki. he died pointlessly making sure sasuke would stay evil and keep on hurting inncoent people. he wanted to give sasuke unbeatable powers so sasuke could use them on konoha. itahci is one of the most self defeating suicidal people ever.
"zomg i love my village so lets give one of its greatest enemies even more power which he will obviously use for evil in his neverending destructive quest for revenge and death"
