I only very recently discovered this game, so my experimentation is still fairly limited. However, I would imagine that there would be some sort of threshold on losing or gaining respect. Like once an area gets to the lowest respect possible, it doesn’t really make much sense to be able to lower it even further, when you don’t get any extra scenes or behavior from the inhabitants. I mean, there can only be a finite amount of variations that the developer wrote based on the respect level. He probably didn’t want people to feel like they were wasting effort by continuously lowering or raising respect more and more when there was nothing new for them to unlock after reaching the threshold.

Well sure, but the minimum area respect total value (always -100) is not the same as the threshold delta for an individual action (seemingly -1 to -3 for most actions, but some are -12 or even -24 or -36). It's more likely that the dev just hasn't finished including all the actions for every region.
