Luke: “Is the dark side stronger?”
Yoda: “No, no, no. Quicker, easier, more seductive.”
In TLJ Rey takes the path of the dark side in that she gets Force powers too easily, while Kylo Ren has trained his whole life, which is more of the original concept for the light side. The light and dark side’s have literally been inverted in the new trilogy, where the light path is actually the dark side, and the dark path is actually the light side.
