there are multiple questions we need to get in persona 5, so i think yes, and i think it is no becaus in shido's castle, where akechi end up by shido's way of thinking of akechi, we didn't know what happened in his fight
I think it would be kind of cool if they gave an expansion onto the ending where you choose to instead keep the Metaverse the way it is, along with the Phantom Thieves continuing their operations.
The sort of "The Answer" I'd expect from that bad ending would be someone (either from the team or not) deciding that they have to end it for all, and maybe go back in time or something. I dunno.
