But I’m not sure the blame for the entire state of the galaxy can be put on Han and Leia (as a few people have suggested).
Certainly not. I doubt Han failed in such a total and complete way as a parent that he produced Space Hitler II as a son. It’s easy to see him not being present as a father and not living up to the legend he had become, though. He’s also a smartass who tends to blow his top and then apologize later.
Ren’s current state is probably a combination of Han’s failures as a father, Ren’s expectations of him, and whatever honey Snopes poured into his ear, but how did it get so bad that he was willing to kill him?
Yet another parallel to the OT that just seems lazy to me. In order to continue on his path to the Dark Side, Ren had to confront his father, and instead of saving him, kill him.
Ugh.
