In the wake of Nettles' death, Applewhite became increasingly paranoid, fearing a conspiracy against his group. One member who joined in the mid-1980s recalled that Applewhite avoided new converts, worrying that they were infiltrators. He feared a government raid on their home and spoke highly of the Jewish defenders of Masada in ancient Israel who showed total resistance to the Roman Empire. Increasingly, he began to discuss the Apocalypse, comparing the Earth to an overgrown garden that was to be recycled or rebooted and humanity to a failed experiment. In accordance with the garden metaphor, he stated that the Earth would be "spaded under". Woodward notes that Applewhite's teaching about the Earth's recycling is similar to the cyclical perspective of time found in Buddhism. Applewhite also used New Age concepts, but he differed from that movement by predicting that apocalyptic, rather than utopian, changes would soon occur on Earth. He contended that most humans had been brainwashed by Lucifer but that his followers could break free of this control. He specifically cited sexual urges as the work of Lucifer. In addition, he stated that evil extraterrestrials, who he referred to as "Luciferians", sought to thwart his mission. He argued that many prominent moral teachers and advocates of political correctness were actually Luciferians. This theme emerged in 1988, possibly in response to the lurid alien abduction stories that were proliferating at the time.
