Jealousy is an emotion of envy mixed with resentment and hate. It's considered one of the most negative and destructive of emotions, capable of serious mental effects. It's one of the best known emotional situations, even found in the Bible. It's also one of the most common motifs of media stories, and one of the typical motives for murder. Jealousy is always depicted as purely negative, and it has no constructive side or positive motives apart from attacking the cause of the jealousy.
