Still, I'm not convinced Itachi > Jiraiya. It'd be a tough match, but it's hard to say who'd come out on top.
He was there for advising the elders so why would he start a fight there after all jiraya was not his enemy & for sure if he would have stayed there fighting other ninjas would have come & hence it would be a really big problem since he wasn't there to fight anyone
Same reason he slayed the Clan....
To keep Konoha and the Will of Fire Alive and Strong.
It was PROVED by Madara, that Itachi was actually a Hero of Konoha.
Betrayed his own clan to protect Konoha and avoid a war.
Wanted Sasuke to be viewed as a Hero.
Thus... If you truly analyze the character and the guy Itachi really was, it proves he would NEVER want to harm Jiraiya, since that would only hurt Konoha, the very village he sacrificed his life for.
Makes no sense. Battling Jiraiya would only give Kisame a boner, and Kisame would attack Konoha with waves of destruction.
Why would Itachi want that?
So, he lied to Kisame, and made Jiraiya seem FAR STRONGER than he really was. Kisame listened to Itachi, and believed him.
By retreating, Itachi was actually SAVING Jiraiya, and Konoha as well, without making it seem like he was a good guy.
If Itachi wanted to, he could of Amaterasu'd the entire village, but you heard him, they didn't go to Konoha to start a war.
Itachi was there because of Sasuke.
So this running away bullshit is seriously pathetic.
That is all speculation, unless of course you can find chapters in the manga that say this.
And no, Itachi didn't use Ameratsu because that would go against his entire reason for murdering his whole clan in the first place. As part of the deal with Madara, Konoha was off limits, remember?
And no, Itachi wasn't there for Sasuke, he was there for Naruto.
