Betrayal is a theme that has proven to take one of the more major roles through ones relationship with another. In William Shakespeare’s play, Othello, acts of treachery and betrayal have great dramatic significance. They greatly contribute to the theme that appearance does not always portray reality. This being the most basic thing to follow, Othello fell into Iago’s traps and could not convert back. He slowly turns into the tragic hero as described by A.C Bradley. From Act 1, Othello's implicit trust towards Iago is made clear. He holds firm belief and reliability in Iago's statements and thoughts, confiding in him regularly. “I follow him to serve my turn upon him”. Iago tells this to Roderigo, showing that he intends to betray Othello, by pretending to be his friend and then corrupting and betraying him. The reputation of the King will soon be lost by Iago.

Now, there is no trust that lies between 2 enemies. Territories have been breached. With the used of this intense phrase, it expresses Iago's thought towards one another. Like Iago's jealousy, it is also shown flipped around. "You would be satisfied" said Iago with Othello replying "Would? Nay, I will" This reply from Othello has shown that after Iago has done so much for others, Othello expressed envy through his words and facial expressions. Though it may not seem much, it covers deeply about the relationships one has with another. One now feels unfaithful and betrayed towards the other. With the use of all of these strong techniques and languages that Shakespeare has used, it proves to show that the jealousy that
