The jackal's different feelings toward the merchant compared to the other judges can be attributed to her cunning and opportunistic nature, as well as her role as a neutral observer rather than a victim of human actions.
Firstly, while the other judges—the banyan tree, the camel, the bull, the eagle, and the alligator—all express grievances against humans for their mistreatment, neglect, or harm, the jackal listens quietly and assesses the situation from a distance. Her role as a judge allows her to maintain a degree of detachment, suggesting she has not experienced the same direct betrayal or cruelty from the merchant. For instance, the tree, camel, and bull all lament that they have been ungratefully treated by humans who benefited from them, fostering a sense of resentment. In contrast, the jackal appears to evaluate the situation pragmatically rather than emotionally.
Secondly, the jackal demonstrates her opportunism when she cleverly manipulates the situation to benefit herself. She instructs the tiger and the merchant to return to the point where they first met, implying a desire to peel back the layers of the conflict for her own amusement and potential gain. Ultimately, when she hears the merchant's claim that the cage was open, she showcases her sly nature by insisting on securing the cage again, which seals the tiger's fate and leaves her in a position of power. This is further evidenced by her statement, “When the man freed you, you should have gotten a drink of water and then moved on,” implying that she values cunning and survival over empathy towards the merchant's plight.
In summary, the jackal's different feelings towards the merchant stem from her detached position as a judge and her opportunistic nature, allowing her to take advantage of the situation for her own benefit rather than harboring grievances against humans like the other judges.
