ST "The First Order arose from evil, you did not"

To me, this quote is major foreshadowing for the future three movies. Kylo Ren is redeemable, and probably will be redeemed, ultimately. However, in the Star Wars universe, true redemption usually only comes from great self sacrifice, such as Vader saving Luke(and the galaxy) from the Emperor. Therefore, I think Kylo Ren's redemption and death is an almost certainty. I think this could happen as early as the end of Episode VIII, so that we can see the effects of his death on other characters(especially Rey and Leia). I could see this causing Leia to turn to the dark side as she loses Han and Ben/Kylo Ren in a short period of time, and it would be cool to see Leia as a major villian in episode IX.
