"I actually kind of understand that." Luke nodded. He still always felt that his father was part of him. The darkness, the person who forced his way out after his foolish actions with the reborn Palpatine. The darkness is always part of him.

"Certain things may always be a part of us, but we can learn from them, grow stronger. I think if it leaves us completely, it might lead to more mistakes in the future. It's not easy living with the things that are a part of us, and we have to keep them under control, but maybe they ultimately lead to us being better as people."

Luke would always fight the darkness and it would always be a part of him. But he would let his past remind him of what he needed to avoid in the future.
