Xanthipe - so we have sunk to the level of dismissing people's arguments on the basis of a spelling error have we?
cold steel - This is the 21st century. Why are you still stuck in medieval superstitions?
There are evil spirits that are unembodied, which is what Satan and his angels are. There are others that are disembodied spirits, people who lived on the earth but either fear damnation if they move on or who just don't want to move on. These spirits are not able to take a person's life, though they can make people miserable. They also, through the power of suggestion, try to entice people to murder.
Really? What evidence do you have for these outlandish assertions?
