What is your theory on why the Elite worship satan?

I doubt all of them worship Satan in any sort of organized way, but of the percentage that do, I would wager that from their point of view, Satan is a sort of ideological symbol for freedom to do as they please (the little self usurping God's throne) -- including those actions and behaviors that occur at the expense of others. Satan is a universal symbol for temptation, carnality, and the force of temptation or manipulation of others to do what they want them do. A big part of negative polarization is the adept learning the fine art of sidestepping natural law (i.e. karma) by getting others to do their dirty work for them. This is why they go to such extraneous lengths to get others to enslave themselves by their own free will choices. They don't have to suffer the karmic backlash for it if another chooses it (i.e. it doesn't damage their polarity). They try to stay high enough on the totem pole to use their underlings as a sort of spiritual "meat shield". Hence their recourse to the Satanic ideological symbol of honed influence or temptation.
