eh sasuke ran off to the dude that killed the third hokage. strike one
sasuke attacked a kage summit with the five great leaders. strike two
sasuke killed the hokage candidate ( yes a few people in the nv knows danzo is evil but have no proof of it) strike three he's out.
sorry dude kiba, hinata and sai have a higher chance of getting hokage than sasuke.
After Sasuke killed Deidara, Orochimaru, and Itachi (sort of), a group of random Leaf-nin (no bias) were willing to let him back in after betraying the village, attempting to murder Leaf-nin repeatedly and joining a missing-nin. They can do the same thing again. Sasuke attacked Bee (who probably won't care at all) and the Kage. Then he helped saved the world by defeating Kabuto, bringing the Hokage back (I've lost count how many times they've saved the Alliance), and wants to kill Obito. It's the same thing as before. Some Leaf-nin might want to forgive him. Moreover, Sasuke is a powerful ninja who you might want to have on your side just in case, not 6 feet under.
As far as killing Danzo, a lot of people know he was evil. The people in power (the ones who have the power to pardon Sasuke) know Danzo was evil. He killed Danzo while Danzo was being hunted down by the Mizukage for mind controlling Mifune and fleeing the Five Kage Summit.
A is the one that will want Sasuke's head but 2 chapters,he was doubting his worldview. Naruto tnj is inevitable
I agree he won't become Hokage but he'll be back in the Leaf by the end in my opinion.
