She doesn't actually know how powerful he is, does she? She wouldn't even imagine such a silly excuse as "he fell in battle" nor think she could fight him otherwise. Her idiotic villain plans are centered around a complete misconception about the situation and the people involved.

30 points. The demon lord being human alone would not be enough reason for Dylan to quit. One piece of information she may be unaware of that limits her understanding is that he kept in contact with the king through reports. If Dylan divulges that, she should be able to link his reasons to the politics and proxy battles between countries. Or in other words, he called BS on the whole mission, and refused to be a pawn.

This is not spoilers, this is a play-by-play of a battle of information. Any amount of extrapolation relies on making certain assumptions, thus can be entirely barking up the wrong tree.

Or, alternatively, monsters are fleeing a highly successful country at kicking their asses and the whole "demon king" thing was made up to get public support to try to cripple a strong rival.
