I believe V has been "struggling" with demonic possessions, too. His erratic behaviors are not just caused by some mood swings... His eyes (like Jk's) often "reveal who is inside his body & spirit at the moment..."
I think all members of the betees for that matter, have spiritual struggles in regards to "demonic spirits possessing" them esp during their performances...
Demonic possessions could happen when human beings allow or open "entry points" of demons into their lives...In betees' case, they had "opened entries" via occult practices, witchcraft, casting spells, using satanic symbols esp on their bodies ( Jk's tatoos of devil's horns, one eye, etc ), flashing satanic gestures, performing rituals, telepathy, pornography, etc.
These are some of the portals of demonic entries, when allowed, strongholds are created, and possessions take place...
