Getting back to the nature of the Maker, may be the clue is in the name. It only makes/creates and it goes against its nature to destroy what it created. Anyway it was more that it was disappointed in what the spirits did with its creation rather than it wanted to wipe the slate clean and start again. So it tries and different model to see if that works out better. Then the creations in the material world seem to have a bad influence on the spiritual, in that the spirits start picking up on emotions and identifying with them, then it works back the other way that the more powerful ones start influencing the source of these emotions.
The morality of the Chant would seem to be the Maker saying, "this is how you were meant to behave to each other," and thus what attracts him. For some reason what can only be described as more benign spirits seem harder to interact with than the malign ones. From what we have been told, some of the most powerful of spirits are the faith spirits. These are the ones that can achieve the greatest healing power. This may not be simply physical healing but mental as well. What particular attracts them is not stated but they do seem to help those who have great belief in helping others, in using whatever talents they have been given, including magic, for the good of others. The spirit inside Wynne was extremely powerful in the Fade against the demon but only after Wynne seemed to have experienced a moment of doubt, others had to intervene and then they were at risk. I've never been sure if it was simply the spirit in her taking over because she no longer had the mental strength herself or whether concern for the others broke through Wynne's despair and allowed the spirit to act.
The fact is you cannot simply say, or the Maker or whatever failed to act because there does seem to be some sort of co-operative action involved. I actually feel that the elven Creators were in fact powerful faith spirits. This is why when elves appear to demonstrate loyalty to their beliefs, they feel the gods have responded. The Creators seem to approve of the same community spirit that is contained in the moral parts of the Chant of Light. All the various facets that they are meant to represent involve teaching and helping the elven community. May be their absence in the time of need in Arlathan and the Dalish insistence of remembering what it is to be elves is based on a dim racial memory that at some point their leaders at least "forgot". Was it that in the face of human aggression they turned to less benign spirits to aid them in their fight?
Fen'Harel is of course the exception to this but then he is acknowledged as such. He seems like a spirit of paradox and irony. May be he favours self sufficiency and self interest. He doesn't seem to be on anyone's side in particular - just acts as the mood takes him to keep things interesting (for him).
Most of mob violence occurs when people are afraid. They were afraid of the big horned giants in DA2, which is how Petrice and others could manipulate them. In Asunder the villagers had heard that a mage had attacked the Divine and this followed on from a mage girl (possibly the one Cole kills) burning down the family farm house, with her family in it. Their ring leader listed a string of events linked to mages in their area, so this would account for why feelings (particularly his feelings) were running high but the basis for those feelings was fear. Obviously his expressed opinions seemed to reflect what he had been taught, that phrase "curse" came up once again but nothing seemed to have occurred in their areas to dispel that notion. Nevertheless when he stated "the Maker would not allow it", Evangeline, who knows the Chant very well, was quick to correct him. The thing is mob violence occurs everywhere, it is the result of prejudice exacerbated by fear or hate that seems part of human nature. Religion is not to blame any more than race, nationhood or what team you belong to.
The prejudices against magic are not solely down to what the Chantry teaches. There are strong historical reasons why people have a fear of mages. Many villages would be able to quote incidents, like the one in Asunder, where the community has been harmed by magic. There is also the continued existence of Tevinter to inspire fear. If Dorian could be successful in his crusade (which I think extremely unlikely on the facts I have read thus far), the corruption at the heart of government was removed and Tevinter became a shining example of how a mage run country benefitted all its citizens, not just the mages, then the fear in the rest of Thedas of mages returning to power would be unjustified. As it is, I understand their fear even though I, as someone who prefers to play a mage, suffers by it. I don't think the Circles in their current form are the answer. I think the Dalish do have something to teach with regard how mages can happily co-exist with their community and benefit it. It is part of the reason why I want to encourage them to engage in a co-operative rather than isolationist future and why I have been pondering if there is a way of reconciling two sets of beliefs to allow them to co-exist in one set, so that no one is forced to surrender their faith.
Solas doesn't have to be Dalish to know what happens in a particular area. He just goes there, lies down and starts experiencing the memories of the place. That is why I hope he is going to throw some light on events in the Dales, since we are going to be visiting there and the fact that his favourite phrase concerning the history of the relationship between elves and humans is that "It's complicated." Humans and elves have worked together in the past towards a united goal for the common good. I'd like to think it might be possible again.
