Yet again, that's only the Christian view and has no basis in reality.<quoted text>
Demons don't always mess, with those they already own.
Although demons are real. I have a true story on those, that happened to me personaly, but no sense in sharing, since it would just be dismissed.
Demons can and do posses the lost of the world, they Cannot posses a child of God, but they do try and hinder them, by using others, or directly tempting them. Before I was a child of God I would usualy beat the demons to the worldly places I would go. Yet just like God -Demons take the blame many times, when it was only flesh that was involved.
In reality, "Satan" (not really the angel's name) is only mentioned ONCE in the Tanakh, as an angel that was given permission by G-d to "harass" Job, and is used BY G-d to fulfill His divine plan.
"satan" is a metaphor, and demons dont exist. IMHO of course.
