This is totally Luke from the original movies. He has a high degree of ligh-side growth pontial (the ability to do a lot of good), but also rides very close (45%!) to the dark size, and is constantly tempted by it, both inside and out. Add on the fact that he lost his hand to Vader in ESB. I think it is quite conclusive:
I am Luke Skywalker. Hear me roar.
