It has been argued by critics that up until the end of the play, Othello fails to realise his own guilt. Do you agree?

Without a shadow of doubt, I agree with the critic's views of Othello never realising the part he played in the disastrous outcome of the play. Ill fate, his mistrust for Desdemona, and Iago's sick, pointless arts definitely did play their parts in the tragedy, but, up until his last words in his final soliloquy, Othello never realised his guilty role. Othello's biggest flaw was that he let his emotions run the show. He never …

…his evil hands. Iago didn't put a gun to his head and command him to kill her. He then says "Like the base Indian, threw a pearl away"-5/2/349. I fell this gives a big indication of him not understanding how selfish and guilty he was. Othello's saying here that in murdering Desdemona, he threw away his most precious possession. He's not realising that he took someone's daughter, someone's friend and most importantly, someone's life.
