Without context I have no preference.
I will say the amount of demons involved can affect something.
If theres only twelve demons and theyre all evil, thats fine. But if theres hundreds of demons, all demons being evil would become very boring assuming demons are constantly showing up.
A case where all demons are good or misunderstood would probably be too much a stretch. Even if the demons may have once had goals or ideals perceived as good, some of them should have fallen to some degree where theyre clearly evil, even if the demons themselves are unaware that theyre evil.
