Iago feels that Cassio's promotion should have gone to him. He envies Cassio.
Iago says that he was sleeping next to Cassio and that Cassio was having a dream about making love to Desdemona.
Iago advises Cassio to ask Desdemona to plead on his behalf. This will help Iago poison Othello's mind, as Desdemona will appear to be doing so out of her (illicit) love for Cassio.
Othello was just out of earshot when Iago talks to Cassio. He has told Othello that he is talking to Cassio about Desdemona but he is really talking about the woman that Cassio is really having an affair with, Bianca. In 'Othello' Iago tricks Othello by planting Desdemona's handkerchief in Cassio's room.
Iago has been passed over for a promotion. Cassio got the promotion to Lieutenant even though Iago had more time in service as a soldier. Cassio got the promotion over Iago because his learning included theory and strategy whereas Iago's did not.

Othello said that Iago is such a loyal friend to Cassio that Iago told about the fight in a way that looked better on Cassio. Even so, Othello fires Cassio and understands that Iago did what any friend would do.
Lieutenant.
It would make it seem that Iago did his part in the plan, where Iago kills Cassio and Othello kills Desdemona. Even though Iago got Roderigo to do it for him.
Iago believes Cassio is not suited for the position Othello has given him because he perceives Cassio as inexperienced and lacking the necessary practical skills for military leadership. He views Cassio's charm and good looks as superficial qualities that do not translate into effective command. Additionally, Iago harbors resentment and jealousy towards Cassio, seeing him as a rival and an obstacle to his own ambitions, which fuels his desire to undermine Cassio's reputation and position.
Iago manipulates Cassio by exploiting his insecurities and orchestrating situations that provoke conflict. He strategically gets Cassio drunk, leading to a brawl that tarnishes Cassio’s reputation and fuels his defensiveness. By planting doubt and confusion, Iago intensifies Cassio's argumentative nature, making him react impulsively to Iago's provocations. Ultimately, Iago’s deceitful machinations push Cassio into a position where he feels he must defend himself, leading to further discord.
Iago's plan is to make Cassio drunk and get him into a brawl that will ruin Cassio's reputation and cause him to lose his position. He urges Roderigo to provoke Cassio "to put our Cassio in some action/ that may offend the isle." As usual,Roderigo is duped by Iago's manipulative words and agrees to do this, even though all he ends up with is a sound beating from Cassio. Iago, however, succeeds in getting Cassio dismissed from his lieutenancy to Othello, which plays in toIago's master plan to ruin Othello.
He killed Roderigo.
