demons and antichrist etc.
Now that's an interesting curve, friend! I can see where you might be going with this...
I'm gonna say yes, on the basis of there always being a bit of human will involved in possession, at least in the beginning. Many have gone a little farther and gone into partnership with their demons, but I know you are going to ask me to back up my view with scripture, and to be fair, I don't know if I can; I will study on it and see whether I can be prepared for your return volley.
I also need to look at the passage again, because it seems to me there is something interesting here you may be heading toward.
