Did we watch the same movie? He didn’t kill him, and didn’t want to kill him. He felt the pain of all the people Ben would kill in the future, and rushed to their defense. And when he realized what defending them would entail, he turned off his saber. He was not willing to kill his own nephew, even to save the lives of many.

This is the dark side of the Force. It tempts you to be reckless, to act on emotion, and to let the ends justify the means. Luke resisted the temptation, this time. If he had been trained more thoroughly in the Jedi way, and learned to suppress his emotions from childhood, he might have caught himself before rushing out of bed armed and ready, and the vision might not have come to pass, but this is a difficult task for a mostly self-trained Force user. And, let’s be honest, he is also the son of the legendarily hot-headed Anakin Skywalker.

Horrifically stupid Disney writing.

Luckily Disney Star Wars is not canonical.

cute, i chuckled.

TLJ is second only to ESB in the saga.
