About this deal
Snoke approved, believing that the new name represented Solo's true nature and would become known to the entire galaxy one day. Unfortunately, instead of preventing it, Luke caused Ben's fall to the dark side, as Snoke and Palpatine preyed on Ben's internal conflict. Carry on his grandfather's legacy and finish what Vader started (succeeded, but not as initially intended).

During their final battle, Rey "kills Kylo Ren" soon after Leia's death but saves him using Force healing. His piloting abilities are shown to be superior when he is running away from the three students that survived the Jedi Temple destruction, as he makes an attack run in which his fellow apprentices soon realize they won't be able to evade.San Tekka had invited Skywalker to travel with him to an archeological site on Yoturba, and also noted that Solo could benefit from his Master's absence by taking on more responsibilities at the temple. The only reason he did so well was because of an injury Ren endured earlier and also the fact that he was emotionally unbalanced because of Han's death.

Kylo has seemingly become far worse than his grandfather; although Vader was brutal and ruthless, he did genuinely care about his family, ultimately leading to his redemption. He finally overpowers Rey during this fight, bringing an exhausted Rey to her knees, but he ultimately loses the duel and is gravely injured by Rey because he becomes distracted upon sensing his mother's death. Though Solo would not speak of him in detail to Ren, he remembered the way Tai encouraged him to be himself despite the pressure of being who he was—the scion of a legendary family.
Shortly afterwards, he was still able to overwhelm Rey, in the end losing because of his conflict, weakened state, and unwillingness to kill her. Because of Snoke's and Sidious' corruption, he believes that his feelings of attachment towards his family are a weakness. As with Snoke, Ren was doubtful that Skywalker died by Solo's hand, although Solo confirmed that at this point he was responsible for the destruction of the temple and deaths of other Jedi.
