They had a good relationship - Othello trusted Cassio and Cassio respected Othello
In Shakespeare's "Othello," the titular character explains Desdemona's affection for him by attributing it to his compelling life stories and experiences. He believes that she has fallen in love with him for the tales of his past adventures, hardships, and the exotic nature of his life as a soldier. Othello suggests that her love is rooted in her admiration for his resilience and the narrative of his life rather than mere physical attraction. This perspective underscores the theme of racial and cultural differences in their relationship.
Iago wants Desdemona's handkerchief because it serves as a crucial piece of evidence to manipulate Othello into believing that Desdemona is unfaithful. The handkerchief, a gift from Othello, symbolizes their love and trust; by obtaining it, Iago aims to create doubt and jealousy in Othello's mind. This manipulation is part of Iago's broader scheme to destroy Othello and achieve his own ambitions.
Iago doesn't like other people to be happy because he is so unhappy himself, notwithstanding the fake "honest Iago" persona he has developed. Since Desdemona is happy in her marriage to Othello, Iago wants to destroy her in the process of destroying Othello.
Cassio and Othello were very close friends before the play.
Desdemona's father, Brabantio, is upset about her marriage to Othello because he feels betrayed and believes that Othello has used witchcraft or manipulation to win Desdemona's affection. As a Venetian nobleman, he harbors racial prejudices against Othello, a Moor, and is distressed by the idea of his daughter marrying someone outside their social and racial circle. Brabantio's anger is compounded by the notion that Desdemona has defied paternal authority and societal expectations.
Desdemona exhibits qualities such as kindness, loyalty, and innocence. She is portrayed as a devoted and loving wife to Othello, displaying patience and understanding in her interactions with him. Desdemona is also known for her boldness in defying societal expectations by marrying Othello against her father's wishes.
