In addition, literature also appears to be the reflection of the thoughts and ideas the author maintains and expresses the same in the light of his/her profound observation about the natural and physical phenomena existing all around. Consequently, it aptly appears that the authors of one and the same era produce divergent thoughtfulness, while the writers belonging to different eras could share one and the same ideology while creating their works. The same is applied to the under-consideration literary pieces including Othello, Wuthering Heights and End of the Affair, due to the very reality that all the three literary pieces focus upon the feelings of jealousy prevailing in the human breast against the rival, enemies, and opponents through their protagonist characters and their challengers.
Jealousy serves to be one of the essential elements of human nature, which is observed by almost all humans, though its nature and intensity varies from one person to the other. The psychologist-theorists have also declared it like normal human behavior, which urges the desire of competition and combating with the rivals in order to meet targets and achieve goals during the course of life. Men and women, according to Buss (2000), are primed to perceive subtle indicators of potential infidelity, which in turn trigger jealousy suspicions. As a result, the fear regarding losing someone or something precious for one produces feelings of jealousy, which ultimately urges and instigates him to take revenge from the person(s) responsible for causing the loss and depriving him of the person or thing he longs for. Since the writers appear to be one of the most sensitive social strata, they observe and perceive the slightest .feelings of jealousy appear in the wake of the financial, material and emotional losses the individuals experience in their life.
