Prime Clone
Super Freak
I can accept that, by it really does downplay the Jedi/Sith, especially one that was trained by Luke Skywalker and seduced to the dark side.
We don't know how far Kylo got with his training, or if he's had any since. That could also be the source of his conflict.
People gotta remember there's a whole backstory being hidden kept from us until later. That much is clear from the very first scene.
As I said earlier, it bugs me there are some obviously pivotal events that won't play out in the primary SW films (unless they do flashbacks). Kylo's downfall and Luke's exile are too big to leave to the anthology films, or worse, books and comics!
Still, maybe that's all part of Lucasfilm's plan.
