Lodivico is a kinsmen to Brabantio, Desdemona's father. He serves as a witness to Othello's jealousy when Desdemona says she has "love for Cassio." Othello, thinks his wife means she is romantically involved with Cassio when all she means is she is concerned for him. Othello hits Desdemona in front of Lodivico and this, of course, causes Lodivico to question Othello's behavior and sanity. Lodivico also witnesses Othello's arrest when people realize he has killed Desdemona. Having no idea of Iago's real intentions, in Lodivco's mind, Othello is guilty of murdering a member of his family and is not to be trusted.
