Well now this just goes on and on doesn't it.
Firstly Satan was handling procreation. The go forth and multiply was delegated to Satan. So the continued existence of the human race lies in the hands of Satan not God. The Devil handles sex and that's also the brain stem.
Jesus Christ was the result of the combination of Mary and the Holy Ghost, but as Satan handles reproduction and as Jesus Christ's birth proves the reproductive act Satan must have been involved and thus the Holy Ghost in this context would have to be demonic and thus Jesus Christ would then have to be half human half demon hence his power. The entire Christian religion is based on a hybrid. Not to mention Adam who was supposed to associate sexually with Lilith as the originally intended wife - Lilith obviously being a demoness.
Now it seems that Satan has died and largely because of God and 'Good' this the cortex of the brain which is then undermining the brain stem. That in turn destroys the power that was making the world male dominated. The death of Satan may have caused feminism, and is now hitting procreation.
Meanwhile Satan's replacement Cupid the only religious power with similar ability, is sitting in the limbic system of the brain undermining both the cortex and the brain stem - while attempting to convey the evil satanic powers decended from the former Satan by way of children, as Cupid is largely a child himself, thus kiddie porn etc. The evil forces are being realigned to focus on the children.
And then... if there is an archive of the hive mind of Satan which can restore the damaged brain stem while accidentally attempting to resurrect the dead Satan, who then emerges as the ghost of Satan, the power of which cannot be taken up by Satan himself due to his death, becomes localised around the individual doing the hive mind restore from the backup - who then becomes 'The Son of Satan' acquiring the legion of demons locally decended - this being Neo-Satanism (as there is no Satan to worship). You then have a surge towards Neo-Satanism as a means to continue the reproductive cycle of the human race. That being pinned to the archive of the hive mind the backup of Satan, which could well be the works of Mozart that you cannot then ban to prevent that result.
You then have a very scary looking world where the Universal power of Satan is localised to the planet, where individuals could potentially acquire the Satanic power in an order of magnitude that would be like three solar systems worth? If any of this stuff pans out the results would be catastrophic.
