Billie asked for this, in "bury a friend" she said she couldn't say "no" she was tempted, knew right from wrong, gave in anyway. Also, she's one of the goat heads that will be separated from the sheep on Judgment Day. All of these satanic celebrities will be included in that category. People who know the truth should stop being worried over them, and focus on their walk with God instead. These were destined to be on satans side for Gods will that we may be tempted and tested with our faith by their music and entertainment, etc. Many are under spells, Gods people fall and get back up nonetheless we get tempted, but refuse. To me, it isn't pleasurable nor sad that they're in this, it's just "Oh well." for me. They enjoy what they get, they may have regret everything at first but as they get used to things, they'll see it as "whatever" and also, it's not like Billie is innocent in this and her handlers are the ones that are guilty, the entire group is.
On Judgment day, I strongly believe God will mention to any satanic famous person, "You've deceived millions/billions with your entertainment" and etc until they get tossed in the lake of fire. They'll be fearful and dumbfounded when he mentions this. This is why you need to focus on God, get away from worrying over the damned!
