roderigo dies
During the brawl, Iago kills Roderigo.
Roderigo was in love with Desdemona, who married Othello instead.
Roderigo and Iago have several long conversations in which Iago responds to Roderigo many times. The question needs to be more specific.
Roderigo is mad hater
Roderigo pays Iago large sums of money to help Roderigo's attempt to woo Desdemona. Iago just pockets the money because not only is Desdemona totally committed to Othello, but could never be interested in a twit like Roderigo.
Iago has been systematically conning Roderigo out of his money, saying that he is using it to try to get Desdemona to dump Othello and go for Roderigo instead. Iago knows that Desdemona will never do this, and has been simply pocketing the money. Roderigo is starting to catch on, so Iago feeds him the same line about Cassio and Desdemona having an affair and sets Roderigo on to murder Cassio. His objective is to get rid of both of them. Roderigo does stab Cassio, who Iago takes for dead, so Iago kills Roderigo himself.
Cassio and Roderigo fought primarily due to Roderigo's jealousy and desire for Desdemona, compounded by Cassio's appointment as Othello's lieutenant, which Roderigo resented. The conflict escalated when Roderigo provoked Cassio, leading to a brawl fueled by alcohol and misunderstandings. This confrontation ultimately sets off a chain of events that propel the tragic narrative of Shakespeare's "Othello."
