Luke’s fight with Vader was defensive until he mentioned Leia. Then he lost it for a good 30 seconds or so of emotional anger slashes complete with operatic background music.You could argue his fight against Vader in RotJ was more defensive than offensive. Once Vader was weakened enough he stopped. In TLJ he was going after someone in their SLEEP even if only for a second. Also his experience with Vader would’ve taught him that anyone can be brought back to the light. Ben hadn’t even fully turned yet and actually still hasn’t fully turned since his conflict with a pull to the light is still an important plot point. If Luke could sense that conflict in his father he would’ve sensed it in Ben and would’ve known he could still save him.
That emotion that he pulled himself back from in Jedi is the same emotion he experienced with Ben. It’s not something he’s thinking about it’s something that he’s feeling and pulls himself back from. The difference is that he had the chance to pull back from it with Vader. Ben didn’t give him that chance.
