Hi Anon! And nope, not really, because Dragoneki woke up due to Mutsuki attacking him right after he went to sleep and anyway, Hide said that Chigyou predicted Dragoneki would need to physically rest at some point. 

So, maybe I’m wrong, but I think that more generally “inactivity” might become Kaneki’s new creed for the following arc to come, because…

More than simply pushing him to blame himself though, what Rize is saying is that if he keeps on fighting, he’ll trigger the death of more people that he loves, which is why Kaneki concludes that stopping here is what will allow him to protect what’s left of them.

So “Rize” (who again is himself) is introducing the idea that “passivity” should be his new way to protect the people he cares about. As such, I also agree with @hamliet​ that “Rize” might eat “Kaneki” next, as an opposite parallel to the Aogiri arc when he “ate” her to gain her strength (I mean, if he’s going to stop doing anything, then he doesn’t need strength anymore, right?).  

Back to the reality world, it might simply be translated into Kaneki 100% blaming himself for becoming a monster and not believing that he’s able to change the world, just like he was supposed to do…

• first in TG, as the first artificial OEG who was a part of both worlds, as described by Yoshimura
• then in :Re as the OEK.

However, more than learning from his failures and not even realizing that the Dragoneki situation did allow humans and ghouls to work together for the first time, Kaneki will probably stick for a time to the fatalistic idea than nothing can change, just like Touka currently (so they’ll be a set there again in this possibility). 

Of course this won’t be his final stop point in his development journey, because V will be his shot at getting redemption for what he did as Dragoneki, by protecting everyone and finally realizing how useful he is:

However, if V threatening everyone isn’t enough to do the trick and motivate him because he’ll still be scared to fuck up and cause more death, then Kaneki (and Touka) realizing that changing the world is necessary for their baby’s future might once again allow him to find his resolve:

So “Rize” is basically parroting what Kaneki heard from Furuta in ch143 and this chapter is just a continuation to ch144:

• when fighting against Arima in Cochlea, Kaneki was ready to just let himself die, but then he decided to live on and to take on what Eto and Arima were expecting of him, because he had nothing else to live for.

• Meanwhile in the current arc, Kaneki doesn’t want to die anymore, but “Rize” (who is just a part of him) is pushing him to believe that he’s so useless that it’s better to stop fighting in order to avoid more death.

In one way that seems pretty grim and depressing, but I’m personally super glad that it might have laid to rest all the femtoneki theories. x)

I hope it makes sense, have a nice day Anon!
