Its been lampshaded pretty heavily that the demons have been evolving closer and closer to humanity over time. They started off as purely unthinking animals that mimicked human voices as bait.
At some point, they started become more intelligent to trick humans better.
This has lead to them becoming more social as they internalize more human concepts. The GOAL of that internalization is still to trick and prey upon humans, but the side effect of that adaptation is that they still become closer to humanity. First in mind (we see older demons that are clearly intelligent, but look like horrible monsters) and later in body (modern demons look like pretty people with horns to better blend in and gain human trust before their betrayal).
If this trend continues, at some point they will have fully THING-ified themselves, and become something that mimcis humanity so well that it becomes indistinguishable from the thing it is copying, having evolved their predation of humans out of themselves because they have reached a level of intelligence and socialization where they are now able to understand concepts like malice and choose not to eat people instead of being a slave to their inherent instincts.
When this happens, the conflict is going to arise from the fact that when 'good' demons start to exist for real, Frieren *won't be able to believe them*. As long she judges them based on her past experiences with other demons, she will never be able to see their existence as something other than a ruse, even if its become genuine.
