Her nave conception of love is apparent in Act 4, scene 3 in her conversation with Emilia regarding adultery. Lovesick and confused, Desdemona expresses her belief that no woman would actually commit such a crime. What is implied is that she would never (ever) do such a thing. This goes to show the profound feelings that she had for Othello. These feelings would have been tested when Othello came to her room to "sacrifice- her. Desdemona is so deeply in love with Othello that she does not implicate him in the last words of her life, which were spoken to Emilia. When Emilia asks Desdemona who has committed her murder she replies, "Nobody - I myself. Farewell- (5.2.122). She is evidently defending and looking after Othello -even though he has just murdered her. This is Desdemona, ever the dutiful wife. .
As Desdemona becomes increasingly aware that her love has turned sour with jealousy, she falls into a state of hopelessness. This depression and the shock she experiences in the final scene surely influenced the outcome of her character. For when one is depressed (as is often the case when love is lost) it is possible for that person to lose their will to live. Depression leads to suicide in some cases. It is far fetched that Desdemona's death was a type of suicide, but her depression and shock could have made her less opposed to the idea of dieing. Also, as she loved Othello, her future outlook (life without her love) would have been negative at best.
Much can be said about the personality of Desdemona, and how her persona would influence the decisions that she made at the end of her short life. Firstly, it is apparent that Desdemona is extremely nave. This has been illustrated in the point that was made above. It is this naivety that is eventually her undoing. Secondly, Desdemona can be said to be a very brave person, who would not be afraid of death. This becomes evident near the beginning of the play.
