But Obito told Sasuke everything, or at least enough. He found out Itachi was quite the cold hearted traitor he assumed and the Village was priority number one. So to honour the memory of his brother... he vows to destroy the village?
The thing that's changed from then to now is Sasuke's motivation. His whole life was revenge, trying to kill Itachi. Once he found out the truth, realized what he had done, he probably overcompensated for killing Itachi, and replaced his super-hate with super-love. "It's the village's fault he's dead!" He was obsessed with his brother, the fact that Itachi loved the village enough to sacrifice himself reads to Sasuke as: "the village forced him to do this." He still doesn't know how to do anything other than enact revenge on things at this point, it's been his entire driving force for years, so he points himself at the village.
I mean it's a shitty situation right there, it's hard to admit that you just killed the guy you thought was a villain after you learn he was the hero. Especially when he's your brother, and did everything for your sake. It's hard to take responsibility for what you've done, so something else has to take the blame. With Tobi there manipulating that whole story, Konoha becomes the scapegoat.
Vs Bee, there's no real target there to hate. Once the Kage summit comes around though, and there's a clear target associated with his brother's demise, he finally gives in to his emotional shit, and via the documented "emotions of loss give the Uchiha their brain powers" explanation, he grows a Susanoo, and goes a little crazy in the process. "The curse of the Uchiha."
Edo-Itachi probably eases the pain of "I killed my brother" a bit. It's a little easier to deal with when suddenly he's sorta not dead. Through their conversations, he starts to come to terms with the idea that Konoha wasn't to "blame" for Itachi's actions, but rather that Itachi made that choice for himself. Edo-Hashirama solidifies that notion, that "a ninja" is someone who does anything for the sake of of their dream, does anything to protect what they feel they must protect. He comes to terms with the notion that it was Itachi who made the decision, that Konoha was worth protecting, that it wasn't a matter of blaming someone for what happened to him.
There are some points in all this that seem pretty abrupt and weird, but I think when you go through it all in sequence like this, it makes a little more sense as an overall arc.
