Based of the latest chapter that was released, Naruto told the Sage of 6 paths that he would end the brothers feud. This leads me to believe that the only way he can technically end this battle between the Uchiha and Senju descendants is by killing Sasuke. Since Sasuke is the last descendant of the Uchiha clan, if he is to die, this will mean that there will be no other reincarnation from Indra's lineage to inherit his chakra, hence ending the battle. The Sage of 6 paths stated that in order to end IT, the powers of both the Rinnegan and all the tailed beasts are needed. The only person who is capable of wielding the Rinnegans power if Sasuke doesn't end up releasing the jutsu himself is Naruto.
To support my theory, Obito who is a descendant of the Uchiha clan stated that he could barely handle the one Rinnegan, let alone both. Yet, Nagato who is part of the Uzumaki clan was able to wield both of the eye's. Logically this doesn't make sense, but considering that Madara physically gave Nagato the eye's, he must of done something that allowed him to wield the eye's without killing him. Also Black Zetsu stated that he tried to persuade both the reincarnations of Indra and Ashura in the past to awaken the Rinnegan, but had failed. So if a reincarnation of Ashura's was also capable of awakening the Dojutsu, Naruto is the only logical person who can actually wield his eye's and potentially even awaken the Rinnegan is Sasuke's other eye as well if he transplants both.
