And Luke came perilously close to killing his own father. Not everybody sees the wrong they are doing, and makes the right choice.
Luke’s father was swinging a lightsaber at him and taunting him with turning his sister to the Dark Side, all while his friends were fighting and dying right out the window.
Ren’s father was touching his son’s face and offering whatever he could to bring him back. He got a lightsaber in the torso for his trouble.
Not really the same thing 😃
