Final answer:
Iago is motivated by jealousy, racism, resentment, and psychopathic tendencies to destroy Othello in Shakespeare's play.
Step-by-step explanation:
Iago's motives for destroying Othello in Shakespeare's play Othello are complex and multifaceted. One significant motive is jealousy; Iago is envious of Cassio's promotion over him and suspicious that Othello has been involved with his own wife, Emilia. Additionally, Iago harbors feelings of racism and resentment towards Othello for being a successful Moor in a predominantly Venetian society, which fuels his desire for revenge. Finally, Iago is driven by his own psychopathic tendencies, taking pleasure in manipulation and the downfall of others without significant remorse for his actions.
