You must convince yourself the world is evil if you are to have any hope of justifying:
- the destruction of innocent children and animals in the environmental ravages of a world-wide flood
- instructions from "God" to kill men, women, seniors, and babies so as to wipe out entire cities and take them over as your "promised land"
- the deaths of billions at the "end of this system of things"
I know I had to.
There's no other way to love, obey, and praise a "God" who could do these things unless you convince yourself it's right and necessary. There's no other way to accept the Bible as the literal, perfect, complete, infallible "Word of God" unless you can rationalize these things. Hence, the world is a hopelessly evil, corrupt, and damaged place which must be destroyed and rebuilt from scratch - with the help of a few select "chosen" who also think it's a great idea, of course.
It just so happens that this attitude is quite convenient for the "upper management" of the Org in keeping the R & F in line.
