Bhagavad Gita, Chapter 16, Verse 8

They say, 'The universe is without truth, without a moral basis, without a God, brought about by mutual union, with lust for its cause; what else?'

A real, specific worldview is quoted here directly, in the demoniac's own words, not paraphrased from outside.

Letting this belief system speak for itself, no absolute truth, no purpose beyond gratification, makes the danger concrete rather than abstract. Real ideas are shown leading to real consequences.
