Re: kakashi-obito thing...
Idk. I'm starting to see a parallel between Sasuke and Obito. Besides them both being Uchiha, both of them seemingly chose a path of evil due to their weird interpretations of traumatic events in their lives.
Sasuke, even after realizing that his brother willingly killed his clan to protect the village, leaving the village as his brother's last legacy, still wanted to destroy it. And after Hashirama and Hiruzen basically telling him the same thing he already knew, that Itachi endured what he did for the sake of the village, he decided to protect it.
Now we find out that Obito knew all along that Rin willingly gave her life for the sake of the village, yet he still wants to tamper with that legacy and create an alternate world where her noble sacrifice didn't even take place, thus taking away the significance of what the real Rin did for the village. I'm sure that after a bit of tnj, Kakashi can eventually do what Hiruzen and Hashi did for Sasuke, and basically tell Obito what he already knows and but put it in a way that Obito finally realizes that what he's doing is stupid.
That's just my opinion though
