I guess I'll counter some of this just because I can. U_U
1. No, not really. I don't remember Obito ever attempting to attack Itachi, even though theoretically if he was strong enough he should have considering that he knew that Itachi would never catch Naruto and was never for Akatsuki in the first place. I just remember Obito screaming and burning from that amaterasu activation and then having to use Izanagi to turn it into an illusion.
2. Yeah, he was pretty scared/cautious of Itachi. That manga panel w/ Obito's statement makes it clear. Kishi made it once again clear in the RTN movie he wrote the script for in which Obito and Itachi encounter each other & Obito decides to run away after Itachi tells him that even with Kamui, there is still a way to hurt him.
3. Everyone thought Obito was Madara until he took off his mask. The entire world was fooled, there is no shame in believing he was Madara. That and Itachi never wanted to fight Obito. He wanted Sasuke to do that and be known as a hero for doing so, that's why he told Sasuke that entire story about EMS. Itachi wanted Sasuke to awaken MS after their fight, then take his eyes and gain EMS when he would start to go blind, then go after "Madara" and take him down so he could be even more of a hero.
4. All the Uchiha fail. In fact no, all the shinobi do. Humans are not perfect and it is only natural for them to do so. Obito was used as a tool his entirely life and noticed that since he went down the wrong path, his life has essentially been totally useless. Sasuke has spent his entire life going after revenge only to find out that he was wrong about everything and that he gets nowhere. Madara lost time and time again to Hashirama and his entire clan betrayed him in favor of the Senju. Maddy is also about to get his ass handed to him by two 17 year olds as we speak. Itachi failed as well, but not nearly as hard as the others did.
5. Ending Edo Tensei helped both sides. Kabuto summoned more Edos, they were just no-names though and didn't get much panel time considering that it would be useless because they had no relevance to the story other than being fodders in Kabuto's Edo army. They would still cause damage though. Also, it benefitted the Edos, considering that none appreciated being used as puppets and forced to fight against their comrades, they wanted to go back and R.I.P.
6. Yeah, that's why he killed his sensei and attempted to destroy Konoha back when he was 14. Obito still did care about destroying Konoha.
7. But it was also a bargain that Obito could have thrown away, he's not exactly a good guy and his word has been proven to be trash before. Itachi apparently had the upper hand judging by Obito's statements and the fact that he didn't attempt to harm him even though he knew he was no real use to Akatsuki and could have been replaced by any other missing-nin.
1. Why would Obito attack Itachi? He was doing what Obito wanted.
All you remember is a trap that didn't work, a trap that Itachi sprung because he wasn't willing to attack Obito himself and save the world.
2. He acknowledged Itachi's capabilities, but he wasn't scared of Itachi.
You're using the RTN movie as proof? You mean a dream world where nothing makes sense? Lovely.
3. I didn't say there was any shame. You are however making a lot of stuff up. Itachi didn't plan on Sasuke fighting Obito at all, Itachi's plan was to try to kill Obito with a trap. You forget that, before Itachi died, he didn't trust in the abilities of others and tried to do everything himself; so no, he wasn't leaving Obito to Sasuke.
Itachi also never planned on Sasuke getting EMS, if Sasuke did then Itachi determined that it was because he went evil and left the crow to brainwash Sasuke.
Now if Sasuke rejected Obito in the cave, then Obito could had killed him. No MS, no EMS. If the Amaterasu actually worked and Sasuke returned to the village, he would had been killed by Pein's rampage.
4. No, humans aren't perfect. However, everything Itachi touched turned to shit. Obito was actually more successful than Itachi, and he also knew that he was being used and that's why he never intended on resurrecting Madara and was going to become the Juubi Jinchuuriki himself.
5. We saw everyone Kabuto resurrected, and they were all sealed with the exception of Madara, Muu, Chiyo, and Kimimaro for sure. Itachi having Kabuto undo Edo Tensei also allowed Madara to gain control over himself.
6. Obito was acting out a plan. Obito wanted Kurama and waited for the right moment to strike, and in the meantime the villagers just thought that Kurama started going wild. Good cover up. What I'm wondering is if framing the Uchiha was part of his plan?
7. Itachi never had the upper hand. Not in power, by Itachi's own confession, and not even strategically. Obito knew everything about Itachi, even though Itachi himself wasn't aware of it. At a moment's notice, Obito could had revealed everything about Itachi, the Uchiha, and Konoha to the world. And while he could had attacked Itachi himself, he also could have just sent Akatsuki to kill Itachi for him. Obito was using Itachi to get what he wanted.
And that's just what Itachi did, help Obito in his goals. In the meantime, Itachi did nothing to help Konoha against Akatsuki. Didn't reveal any information, and didn't lift a finger. He was no real use to Konoha.
