Spoilers if y'all care about that, but Hawke's fate us completely up in the air regardless of whether they're trapped or not.

Sure, it was stated they returned to help rebuild Kirkwall if they weren't trapped in the Fade, but the Inquisitor states that Kirkwall also fell to the Blight caused by the elven gods, and Aveline had to take refugees from the city to Starkhaven to help Sebastian. So if Hawke wasn't trapped in the Fade, why weren't they involved in protecting Kirkwall, or at least helping the survivors?

Considering the fact that the man was willing to kill someone just because he thought they failed him, even before he became a demon, it is highly unlikely Muzan will want to settle for a normal life. His sociopathic tendencies and paranoia won't allow it. What if someone manages to find a way to kill him, despite everything? He's more likely to wipe out most of humanity to ensure his survival.
