For example, adrenochrome harming a pure child of God terrorizing then taking the adrenochrome release just prior to the child’s death to use to create an anti-aging circumstance. 

Demonic is a ‘nature of’.    It is malefic, pleasure from ill-gotten behaviors and actions that directly harm God’s creation.  It is disgusting hedonistic gluttonistic greedy.
