Kylo Ren: Where the Journey Ends for a Fallen Hero

In the new trilogy of Star Wars films, Kylo Ren is a character repeatedly examined as one full of conflict, being pulled in two directions by opposite sides of the Force. At the end of The Last Jedi, he chooses to tear down all remnants of a legacy that has overburdened him and build a new one in its place, seemingly cementing himself in an ill-natured goal that prompts Rey to stop him.

However, it's believed by many fans that he still isn't too far gone, and that enough light exists in him that he could in fact be turned, as Rey was determined to do for much of The Last Jedi. On the other side of the spectrum, one could argue that Kylo going through a redemption arc that mirrors his grandfather's would render Luke's sacrifice meaningless, that his declaration to Leia that "no one's ever really gone" was more in reference to the memory of who Kylo used to be rather than suggesting Kylo is still capable of saving.

Should Kylo be redeemed in The Rise of Skywalker, the final installment in the Skywalker saga? And if he is redeemed, would that take away from the positions the characters decided to defend by the end of The Last Jedi?
