Non-Dalish mages, for the most part, spend their lives trapped and isolated from the rest of the world. I don't think they have much of an opinion on how the Dalish use magic, except to consider it as much of an affront to their religion as they do everything else about the Dalish.

( magical politics in thedas: it's complicated. )

The ones of note who do not are the magisters of Tevinter, who use magic to rule unquestionably.

( and the dalish are different because... well. mostly because in elera's opinion they just are, and don't abuse it like the tevinter mages do. )
