"Demons and devils? Aren't they just synonyms?"
Most mortals didn't know the difference between demons and devils because it was far too rare for ordinary people to meet them. And if they really did come across a demon or a devil it didn't matter which was which—they'd likely end up the same either way, as a soul dragged to the lower Planes.
However, demons and devils were completely different species. Their personalities and habits couldn't be more disparate, and they even viewed each other as mortal enemies. Most circumstances where the two met would end up in a life-and-death fight.
"Those sly devils? Their heads are filled with nothing but schemes and plots. Only weaklings need to rely on such things. In front of us magnificent demons, their weak bodies and useless little tricks are nothing but a joke."
