Hello there, I live among indigenous men with their own spiritual traditions, with Buddhists who have very little regard for outside spirit forms, and was raised a Catholic, although now I follow the traditions of an Brazilian/African religion called Umbanda (its roots are in Candomble and Voodoo as far as I can tell, with a hint of Christ in it), and in all of these traditions, different as they are, believe that demons are evil, even the Buddhists choose to name their few evil deities as demons, such as Mara, demon of Illusion in the sutras.
However, what I have seem more and more often is that demons seem to be willing to help those who reach for them, and for whatever reason, they seem to be much more effective than what all of the aforementioned traditions, minus Buddhism, would call God, I do believe that angels are also at work in here, but this really begs the question: why?
Why is it that they’re overall deemed as evil, but still work with humans in a more gray area, instead of purely evil? Also, what’s the deal with demonic possession? Why does it happen?
