I'm not so sure that that's going to happen, and I'm hopeful that it won't. The tragedy of what is essentially an immensely powerful misfit manchild being unable to overcome his rage, and staying lost, is something the series really hasn't examined before. Vader doesn't count, because we see him redeemed before we ever meet him as Anakin. And the prequels just suck anyway.
In general, I think the Kylo Ren character is greatly underrated. I love that Ren isn't some traditional big bad villain, all power and pure evil. No, he's deeply conflicted, emotionally weak even, and he can strongly feel the pull of the light side (and can even act like a decent person from time to time), and yet STILL chooses the dark, because it's his only way to feel not scared. He's a flawed villain, if you will, and far more interesting than most film villains. By contrast, think about all of the forgettable villains in the prequels.
I'm also a fan of Driver's performances in both films. His work here, especially, is the kind of performance that was sorely needed by Hayden Christiansen in the prequels.
