The GENERAL CONTEXT of such use is:
The term refers to Satan's programming of human society to always be looking for an advantage over one's fellow human beings, in whatever one does, which is Satan's "tool" of competition, which also effectively negates any serious considerations of cooperation (or generally thwarts such), resulting in all the effects of such competition upon humanity, as in the wars, legal battles, sports and other adversarial activities.
