While most fans probably chocked Kylo Ren’s display of self harm in the final act of Star Wars: The Force Awakens to being a byproduct of his extreme emoness, a new video from the folks at Star Wars Minute argues that there was a practical reason for the Darth Vader wanabe repeatedly punching himself in his bowcaster-inflicted wound.
As the video above explains, by punching his wound, Kylo Ren may have been trying to summon additional dark side powers, citing several examples from the Star Wars Expanded Universe in which dark side wielders use pain to increase their power. Although most of the EU is no longer considered canon, Darth Maul was able to survive being cut in half by gaining power from his pain, and as this is still considered in-canon, there is actual precedent for this theory.
That being said, we still subscribe to the theory that Kylo Ren really is just a big emo sourpuss who just enjoys pain, both physical and emotional. Although, it’s not hard to see why Ben Solo turned into such a mopey mess when he had to deal with this sort of stuff growing up:
Leia always thought she'd find a husband on her homeworld
I guess she was looking for love in "Alderaan places"!
She is my pearl Ben
