Etymology
Origin of demonic
1655–65; < Late Latin daemonicus < Greek daimonikós, equivalent to daimon- demon- + -ikos -ic
Explanation
Demonic is a word to describe behavior or people who are extremely evil or cruel. It helps to understand this word if you know a demon is a creature of hell. Demonic has that same kind of hellish, diabolical, fiendish, infernal, satanic, unholy quality. This word should not be used lightly. Stealing a candy bar, though wrong, is not demonic. Truly evil behavior, like being a serial killer, is more likely to be described as demonic. In superhero movies, the supervillains are likely to be demonic, since they are more evil than common storybook villains.
