This is what happens when you lie. You need to come up with other lies to hide your first lie. I believe there always was a "faithful and discreet slave" as long as humanity has been around. And His name is Satan. He was simply a person that meditated to the point of becoming extremely powerful, and became God-like. This Being took an interest in the human race and taught others to meditate and become super powerful, becoming Demons. These Demons worked with us humans, teaching us how to use the universe to our advantage. We were taught magick, and this allowed us to thrive in an era when technology was not even available to assist us. This is how ancient peoples had such powers.
Then along comes the precursor of the Filthful and Disgraceful Slavebugger. Jehovah saw mankind thriving nicely under Satan, and orchestrated a plan to enslave the whole human race. Jehovah chose a people to do this, creating a book of lies and altering history to give us Original Sin (the Original Sin manifesting itself in people seeking liberty). Satan was slandered, hell and death threats were made to obey this new arrangement, and ultimately people were forced into compliance. With the help of Jehovah and his filthy angels, Christi-SCAM-ity forced its way into nations minding their own business. Artifacts revealing the real truth were destroyed, and people had their culture trashed. Africa was trashed, as Negroes were kidnapped and sold to Caucasians in America and Europe as slaves (this is the real racism). Most of Europe was later trashed, leading to the misery and death of millions in places like Russia. Communism was forced on China. Terror in the Middle East reigns. And, now Israel is threatened nuclear war in the event that Palestine continues to want independence.
In addition to this general problem, the witlesses are facing the same type of issues. The witlesses not only slander Satan and His Demons, but they make up these false stories. As people wake up and see blatant evidence that they are wrong, the leaders need to resort to making up new lies to hide the original lies. Additionally, they need to use more threats to force people to believe them. While the witlesses are not going to use nuclear war to enforce their lies, they ruin families and threaten other action (and may one day attempt to threaten breach of contract suits for those not living up to their dedication, citing the dedication as a legally binding contract and their not doing all they can to fulfill it as a breach of such contract). This kind of coercion, terrorism, and ongoing lying is necessary to prevent them from having to confess to their original lies and make attempts to actually fix them.
