Roderigo attacked Cassio but did not kill him. Iago had intended that Roderigo would kill Cassio and then Iago would kill Roderigo. In the scenario you are suggesting, Roderigo is a much more successful fighter than we thought and manages to kill both Cassio and Iago. He would then no doubt have been charged with killing them and might offer in his defence how Iago had conned him out of all his money. Emilia would be able to tell her story and live and it would certainly corroborate what Roderigo would say. Unfortunately none of this would come in time to save Othello or Desdemona, who would both end up dead in any event. Since Cassio is dead, someone else would have to be governor of Cyprus.

Cassio fell to the ground and cell out for help
Cassio and Roderigo fought because Roderigo was frustrated over his unrequited love for Desdemona and blamed Cassio for winning her affections. The altercation was further fueled by Cassio's drunkenness and Roderigo's provocations, which led to a public brawl. This conflict was manipulated by Iago to further his own schemes against both men, particularly targeting Cassio’s reputation and position.
He killed Roderigo.

Iago uses Roderigo's unrequited love for Desdemona and his jealousy towards Cassio to spark his interest in his plan to discredit Cassio. He convinces Roderigo that by helping him, he can win Desdemona's affection and thwart Cassio's advances towards her.

Othello will recieve the blame for the attack on Cassio because roderigo has died and everyone already knows that Othello has enough hatred on cassio because of his jealousy.
Rodrigo is stabbed by cassio and killed. Bianca does not die.
Iago does the plotting alone; Roderigo is his dupe and has no more idea how he is being used than Cassio does. In Act II Scene 3 Iago makes sure both are drunk and quarrelsome and then eggs Roderigo on so Cassio will fight with him, thus ensuring Cassio's dismissal. In Act IV Scene 2 Iago lies to Roderigo, telling him that Othello is being sent to Mauretania where Roderigo will never have a chance to see Desdemona. Iago tells him that this is only possible because there is a competent replacement for Othello on hand in Cyprus in the person of Cassio. Get rid of Cassio, and Othello must stay in Cyprus. In this way Iago dupes Roderigo into trying to murder Cassio in Act V.
He thought Roderigo already had.
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.
No, Cassio did not find out that Iago stabbed Roderigo. In Shakespeare's "Othello," Cassio is injured during a fight orchestrated by Iago but remains unaware of Iago's treachery and manipulation throughout the play. Iago's deceitful actions are concealed from Cassio, who continues to trust him until the tragic conclusion.
