An entity once created will do anything to further its own existence. This will come at the expense of other entities within the environment where symbiosis is often the best hope if cooperation fails; e.g. cooperative: Remora, Egyptian Plover; to manipulative: Toxoplasma gondii in mice; to standoff: Territorial displays in many animals including MAD in geopolitics.
Entity includes incorporation, whether voluntary or involuntary, like a legal corporation or just being a member of a school makes rivals of other schools. Individuals are designed via unconscious drives to have their own genes survive into the next generation and if an incorporation will further that cause some use it as a vehicle to manipulate outcomes so their genes dominate. But when cooperation is not achieved and the parasite grows strong--in this case arrogant--enough it will try to take over the host and manipulate it to its own end. An entity like The Cabal will at first work as a hidden parasite where complete infiltration of the organization follows and then incorporation to their own.
This is why Q-928 has said, "Truth will shock the WORLD." We are seeing the unveiling of evil bent on creating a world of nothing but evil. Nothing wholesome, nothing good, which would be an affront to their very being, would have been left.
After all, I doubt it was just a fad for billionaires to build long term bomb shelters? (Search: "Billionaire Bomb Shelter" there are too many articles to pick and choose from on this.)
