For one to gain the information he has and still be trying to destory the entire village, he is a dumbass, didn't Tobi say he helped destroy the uchiha clan as well? But for some reason he gets a pass while sasuke just stays angry at everyone else. That is very dumb of him. Itachi even spent his last few precious moments acting on behalf of the village, and he STILL wants to destroy it, He's tobi's lil misguided B!TCH right now.
Usually a badass but more recently pretty dumbass.
He's been further in the dark than ever recently, he needs to make his own path, instead of having Orochimaru/Obito manipulate him. Hopefully, after his journey to the-one-who-knows-all, he'll start being Sasuke again instead of Ragesuke.
I don't think Sasuke is a badass or dumb ass. I just believe he has become lost on the road of revenge. In my opinion, Sasuke allowed himself to be easily influenced by Obito. Obito had basically admitted to helping wipe out the Uchiha clan, yet Sasuke still follows his order of capturing the Hachibi. Sasuke character has fallen to far into darkness.
