Really, this entire thing would make more sense if someone else had managed to kill Itachi before Sasuke got there, and THEN Tobidara told him the "truth".
Hatred towards Danzo was understandable, guy ordered the entire clan killed. And up to that point, Sasuke's state of mind works and is acceptable… (sort of)
Except for the fact that he personally killed his own brother, and now he's blaming THAT on others. The one thing Sasuke actually did with his own two hands, that he spent his entire life striving for. THAT is the thing he chooses to blame on everyone else? The thing he chooses to be sad an upset about?
(And lets not even get into his sudden new hatred of Kakashi, whose BEST FRIEND was an Uchiha... and who TRAINED Sasuke. Hell, Sasuke didn't even know jack about Sharingan until he was 12!)
Can't even be excited about him going blind, since Tobidara has a whole arsenal of eyes that can be implanted. Or failing that, new dues ex machina eye evolution that magically overrides the one weakness super eyeball had. Either way, blindness won't last, even though its pretty much the ONLY interesting fate he has left, short of dying.
