Something stuck out in my thoughts, as I was considering some old Star Wars E.U. stories, and that was the concept of duality. You see, too me, Anakin brought forth balance to the Force when he fathered his son, Luke (Leia doesn’t seem to be an overt user of the Force in this current canon so I’ll stick with Luke). In the Expanded Universe, now “Legends”, Luke danced on a very fine line of Dark Side and Light, falling a few times. I know that is an oversimplification but I am not the best writer and don’t the skill to convey anything deeper.
