I wasn't going to say anything regarding it, but Assallya kind of got dogpiled, so I'll say this:

Historically most nations were not like North Korea, and the idea that all of the Middle-East is a repressive hell is false. Wahabi Islam is not, in fact, the dominant form of religion in most Middle-Eastern nations. Recall that prior to the rise of Industrialism the Middle-East was the seat of cultural and scientific progress in the world and the place where many foundation stones for modern mathematics were laid, and while it has lost much of that prominence it hasn't changed nearly as radically as Western media would have you believe.

I'm fine with there being clearly delineated Good and Evil, having a Neutral or Good Demon is a contradiction of terms, but separating the civilizations of the world into neatly defined camps pretty much eliminates any semblance of ambiguity, particularly in a setting concept where our objective is to make peace - when the two combatant factions are literally Good and Evil the only way peace can be won is through genocide.
