I still don't buy his dark side being mostly hate. That sounds like nothing but a plot device to make it more compatible with Kyuubi's hatred. Whenever did Naruto display hate? Sasuke was always full of it, but Naruto never seemed to possess anything but envy, which drove him not to anything resembling revenge but rather petty pranks and other attention catching activities. Those hardly speak of hate.

And indeed never showing any negative emotions again would be too improbable. I merely mentioned it out of my dissatisfaction with how this ended. Furthermore, we have seen Bee conversing with the Hachibi and they have been in understanding with each other. That's utterly different compared to Naruto and Kyuubi's situation right now. Unless it only looked like it in this episode, it certainly seems like the situation is exactly the same as it was before with the difference Naruto stole the chakra. Kyuubi is sealed and there's no genuine dialogue between those two.
