I speak from experience when I say that nobody coming is worse than someone bad coming. Because you at least have someone to take things out on~.

But enough about that. It's way more likely someone good will come. The world is filled with a lot more Frisks than Floweys.

[Given the use of the two names as metaphors, Flowey means there's more good people than bad people. Of note he used his own name to describe bad people.]
