Itachi has always been depicted in Naruto as almost godly. For example, in the fight between Sasuke and Deidara, it flashes back to before Deidara joined the Akatsuki. When Itachi casts his genjutsu on Deidara, he is depicted with beams of light behind him in almost a floating stance. Itachi has also always been completely selfless and done what is right. They never truly did show the extent of his power and he always had a plan for something. Does anybody else see this?
