I wouldn't have minded that but we did already have a moment like this
I feel like if JJ intended to rely on this shot as Kylo's lowest moment, then Kylo's redemption arc needed to start from minute one of TROS. You can't have him hit rock bottom, then kind of just slide right back to his characterization from well
before rock bottom for the next hour of screen time, then still pull off the redemption and have it feel earned.
I honestly don't know what the intent is with Kylo's characterization in TROS, especially now that we've seen so much early concept art of Kylo simply staying evil and being killed at the end, both from Trevorrow's
and JJ's versions of the movie. It really feels like they actually filmed a significant portion of that original villain Kylo movie, and then the decision to go with Palpatine and Rendemption came so late that they ended up having to find the material for a redemption arc amongst all the evil Kylo scenes they'd already shot because there just wasn't enough time to start over.
