Final answer:
Iago manipulates Roderigo into thinking that killing Cassio would help him win Desdemona's love, serving Iago's own purposes in Shakespeare's play, "Othello."
Step-by-step explanation:
Iago convinces Roderigo that it would be in his best interests to kill Cassio as part of his manipulative scheming in William Shakespeare's play, "Othello." Iago's motivation is rooted in jealousy and the desire for revenge. He is envious of Cassio's military position and wants to destroy both Othello and Cassio.
By leading Roderigo to believe that Cassio's death would give Roderigo a clearer path to win over Desdemona, Iago is employing psychological manipulation to achieve his own aims. This premise is reflective of human nature, where promises and threats are made with complexity and sometimes individuals are drawn into actions that have broader implications than their personal desires.
Iago convinces Roderigo that it would be in his best interests to kill Cassio because Iago manipulates Roderigo's emotions and uses his desire for Desdemona to convince him that eliminating Cassio will increase his chances of winning her over.
Throughout the play, Iago feeds Roderigo's jealousy and resentment towards Cassio, making him believe that eliminating Cassio would remove a rival for Desdemona's affections. Iago uses persuasive tactics to exploit Roderigo's vulnerability and create a sense of urgency for his actions.
