"I don't think he broke, just that he knew that choosing to put down his 'saber would give us more time to escape. That Vader would...he'd pause." Emotions are tough, buddy. Luke is hovering around the edge of trying to rebuild the Jedi as they were or just set out on his own path and see what comes of it. (Spoilers: Either way, there's going to be a lot of headaches.)

"I only met him a few times, but he wasn't an easy man to stop or redirect once he got going." That's putting it mildly. Skywalker bullshit wins out in nearly every situation. Only the great and noble Saint Beru managed to contain Luke's innate stupid for almost two decades. "He's the one that killed the Palpatine, in the end."
