Even though Ben/Kylo was apart of the dark side, wanting to be like his grandfather vader. He had a good heart, and you could tell he never wanted to kill anyone after he killed his own father. You could see the guilt on his face. As the movies went on, he started Turing to the good side, and you could tell. And as Rey was fighting palpatine, he came to save her, and when she "Died" He used all of his power to bring her back. He lived as Kylo Ren, but died ben solo. And I will always appreciate him for that.
