Othello Act V Questions

At Iago’s urging, Roderigo attacks… Cassio (oh crap whaddup)
Iago kills… Roderigo (rip)
Iago blames Bianca for… killing/hurting Cassio
Othello confronts Desdemona in her room and…. …kills her…….DUNDUNDUNNNN (rip)
Emilia reveals both… Othello and Iago (get it girl) (Until Iago stabs her but that’s besides the point)
Realizing Iago’s treachery, Othello first… stabs him (rip… not really good riddance)
Then, in remorse, Othello… kills himself (rip)
How does Iago intend to dispose of Cassio and Roderigo? What actually transpires? He planned to have the two fight and hopefully kill each other, trying to get off scot-free. What actually happened: Roderigo jumped Cassio and tried to stab him, but failed. Iago slipped in with the cover of darkness and slashed Cassio in the back of the leg. He sees Roderigo, pretends not to know him, and stabs him….real upstanding guy, eh? oh and he also tries to blame Bianca for their injuries.
How does Iago’s treachery finally work itself out? Roderigo dies, Othello kills Desdemona, Emilia exposes Othello and Iago and their stupidity, Iago kills Emilia, Othello stabs (not kills) Iago, Othello kills himself. Everyone dies. Well except for Cassio (who will take over for Othello), Montano, Lodovico, and Iago (who will be punished somehow but stays silent)
What philosophical viewpoint prevails at the end of the play? Othello makes a point to show that he is concerned with what people think of him. He calls himself a “circumcised dog” and basically internalizes all of the racist comments, ideas, and beliefs that others constantly reiterated towards him (racist outsider, black ram, dog, etc). Lodovico takes a step back and admits that the only thing he can do is share Othello’s story with the world.
