One of the most confusing aspects of Demonology
is the distinction between the terms Devil and Demon.
For the sake of clarification, when someone is referred to as
having sex with the devil, it is safe to assume that it
was with a demon, most likely with an incubus (a demon in the
shape of a human male for the expressed purpose of fornication)
or succubus (the female alternate of an incubus).

The term "demon" is derived from
the Greek word daimon meaning divine power, fat, or god.
The actual translation of demon means "replete with wisdom"
connoting that the demons were highly knowledgeable creatures,
evident in their knowledge of an individual's secretive sins.
Demons were fallen angels who followed Lucifer from his expulsion
from heaven by God to hell. The demonologists heavily believed
that the sole purpose of a demon is "to tempt humankind
into immoral acts and come between humans and God (Guiley
"Demons are usually associated
with evil, but in pre-Christian and non-Christian cultures, demons
were, and are, not necessarily good or evil (Guiley
91)." This is an important distinction to make, especially
concerning demonic possession and exorcism. One of the initial
steps in those cases is to identify if the demon is "good"
or "bad". If the demon is not evil, it still is necessary
to exorcism him, however, it does not become a matter of life
or death for the victim. In addition, the exorcist does not place
himself in the tremendous amount of danger typically associated
with the performing of an exorcism.
