It's more than that, chapter 3 is the chapter that starts with Ralsei telling you that darkners aren't real. That even within the context of their universe then can be thought of as like characters in a video game.

If you felt that playing Mantel was justified because the characters in the game within a game weren't real even in the context of their world, than you could apply a similar logic to the darkners, who themselves, within the context of deltarune, are not real.
