People here tend to think that the entire Cabal is unified into one single cause. I don't believe that. There are multiple factions in the Cabal and each have their own cause.

Yes, I think agree this is most certainly a more accurate description. I think a similar paradigm should also be applied to the CCP, for example.

Everyone is in there for their own benefit

Yes, and no. At the end of the day, the primary and central motivation is for self. However, I also think there are allegiances, and belief structures that allow them to do what they do.

and can only see a part of the truth, not the whole truth.

I concur.

A very instructive study into this sort of structure/dynamic is "The Enigma of Japanese Power" by Karel Van Wolferen. I read this when I was living in Japan many years back. The essential gist of the message is that the system itself is what controls Japan, not any individual, or party, or group.

My estimation would be that Satanic forces (who themselves function in unity only for self-benefit and form factions along those lines) keep the earthly instruments in darkness and limited understanding, because doing otherwise would allow them too much control. Thus: "can only see a part of the truth, not the whole truth."

That said, I'm inclined to think that there are some (on earth) too, who are true believers, who believe in their ethic religiously, in some deluded manner.
