Individuals in Jacobean England were encouraged to be introspective, meaning that they must analyse and improve from the inside by appealing to their own conscience. For example, Othello exclaims, "I had rather be a toad / And live upon the vapor of a dungeon / Than keep a corner in the thing I love / For others' uses" (Act 3, Scene 3). This portrays Othello’s inner struggle, as his perception of his wife’s faithfulness starts to be manipulated by Iago. His haunted conscience is common in most of Shakespeare’s heroes, as they are tormented about which actions to take, seeing this as progressing and journeying towards heaven or hell. This is especially evident before he kills Desdemona, as she notices, "Alas, why gnaw you so your nether lip? / Some bloody passion shakes your very frame" (Act 5, Scene 2). Therefore, the link between jealousy and conscience is important to understand Othello’s descent into raging passions. His character’s journey into jealousy is as much a spiritual journey as it is an emotional one.
