Will Kylo Ren be as powerful as Darth Vader? He is definitely more cynical. After all he did murder his father. Vader went after his son but did not ever kill him. Darth Vader definitely crushes Kylo Ren when it comes to strength. Then again Darth Vader was mostly machine than human. At the end of The Force Awakens Kylo Ren was left lying all beaten up by Rey. It will be interesting to see in the next episode if The Supreme Leader starts turning Kylo Ren into a Machine /Man beast. Needless to say I don’t see how Kylo Ren could ever end up like Darth Vader did with some “Good” in him. I would expect General Organa to avenge Han Solos death.
