answer:
‘The murder scene’ reveals the two facts of Othello’s personality-- the dark, savage the most brutal of the one hand and the emotional, truly repentant human and desperate lover on the other hand. Othello loses all his control over himself when he is worked up to strong jealousy by the subtle machinations of Iago. Othello is extremely credulous and firmly believes whatever Iago pours into his ears. He places absolute confidence in Iago and never sees through his villainies.
Othello’s decision to murder Desdemona is not only rash and reckless but also shows a strange but frightening metamorphosis which has overtaken him. The noble Othello has become ignoble and vile. The reason and commonsense which he shows in Venice has completely vanished. When he approaches Desdemona, he arrogates to himself the task of doing justice, reassuring himself with, ‘This is the cause, this is the cause, my soul’ but what he has decided to administer is just the reverse of it. He gives no chance to Desdemona to explain her conduct nor does he allow her even to say her prayer in spite of her pathetic pleadings. Like a brute assassin he smothers the life out of the innocent creature whom he had been worshipping most devotedly and who was his ‘soul’s joy’.
