"I'm listening," she told him solemnly. "You're not."

She sighed softly, shaking her head. "I don't know how Ben turned into Kylo Ren, and I'm fairly sure no one does for sure except for Ben. But you didn't create the thing that had killed Han Solo, no more than Han had himself. Ben might have perceived some of your words or actions a certain way, but you hadn't set out to create a monster. Snoke had. Snoke is the real enemy here, and I'm not a fool for acknowledging that. Whatever mistakes you'd made in your past don't change how I feel about you in the present. Remember that, Luke."

Granted, she didn't know the full extent of his supposed mistakes, but she still had enough of a pristine image of Luke Skywalker being a hero that even seeing him as an embittered older man hadn't taken away from her conviction that he was one of the good guys.
