There are similarities of the Jones Town cult and the Jehovah's Witness cult in that they both tried to segregate from mainstream society, claiming outside of the established organization there is evil, harm and despair but inside is paradise utopia, where there is harmonious peace, love and happiness..
They both professed that their organization in the future will be persecuted or infiltrated by outside forces to try and break up the organization and that certain steps of action are needed and necessary in preparation for this.
So there is or was an alluring segment of each organization as well a fear inducing segment mentally indoctrinated to build and sustain the organization as they were created..
