Starting a cult, need advice...
I don't know that I'd go for anarchy at the lower levels...that creates an environment that makes your nascent cult unappealing to people who are already struggling to get by. Cults tends to recruit by providing a shelter and nurturing environment to people who are marginalized. They also tend to counter infiltration by maintaining a constant dogma that 'They' are trying to destroy the cult, because it undermines the status quo and provides hope and help to people whom the powers that be in the area (government, criminal cartels, other cults) have a vested interest in oppressing. So you offer a mix of help and nurturing with paranoia.
Call this the novice level of cult membership. They are the public face and first line of defense...they provide an aura of harmless beneficence, and an early pre-screening of anyone who would try to infiltrate.
Then you get into your initiates. This is where you want your bloodthirsty types. They police the novices and each other, culling people who show signs of disloyalty, and take direct action against outside threats, but they're strictly disciplined...attacks against the outside must not be traced back to the cult, policing on the inside must be done in a way that is unmistakably recognizable by other cult members.
Anyone who truly proves their devotion and ability as an initiate may become an Elder...this is where you start with the 'unseen power's stuff and use them to unobtrusively gain control of local government, industry, etc. You can have a higher degree than that, like an Inner Circle or High Council or whatever, that masterminds 'bigger picture' operations.
This is assuming you're going for a mass-appeal variety of growing the cult. If you're trying to make it more of a crimi al organization with cult-like operations, you still need to have that kind of outreach to the marginalized...but in this case, the marginalized are thieves, thugs, etc...you offer them a 'blanket' to operate under, protection from local constabulary, equipment, training, etc...but again, you create a definite Us vs Them dynamic and feed their paranoia about other groups, about how you protect them while others seek to harm them...maybe have the Initiates copycat some other group's style of killing on some of the novices to fuel those fires...
But to create a cult, you have to have some co.pelling reason people would want to join it, and then breed some kind of fear and distrust of everyone who is not in the cult. Reward displays of devotion lavishly, at first, but make it harder for the rewards to be earned, so that you build kind of an addiction cycle and more senior cult members have become so accustomed to sacrificing so much that they no longer question any directive you give. Might even make the advancement to Elder a kind of staged torture, where it seems as though they've been captured by some enemy of your organization...they endure torture and brainwashing, leading right up to the edge of them being killed...then you intercede and rescue them, so they feel like they owe you everything (the ones who don't make the grade under torture can either be killed or returned to the Novices, to help add to the whole 'They're out to get us' paranoid atmosphere you breed to inspire vigilance against infiltrators.)
