Could be regarded as a femme fatale as she mobilizes Macbeth's temptation into evil and mirrors the witches in her desire to influence and manipulate Macbeth
Lady Macbeth later fragments this deceptive facade as she descends into madness, seeking the light metaphorically, seeking the light and hope from God to guide her out of her psychological hell
A shift in power is clear when Lady Macbeth retreats to her weaker feminine role, her ability to restrict her remorse weakens as she is unable to combat her natural weak human nature
Lady Macbeth: '"Come, thick night, and pall thee in the dunnest smoke of hell, That my keen knife see not the wound it makes, Nor heaven peep through the blanket of the dark, To cry 'Hold, hold!'"'
Lady Macbeth enters with a taper, as a taper provides light, it's emblematic of how she's seeking out the hope, light, hope and solace in her eternal mental darkness
Jesus was seen as the salvation for mankind, therefore Lady Macbeth clinging onto the light would be symbolic of her holding onto the hope of redemption as she knows that the violation of the great chain of being, religion and divine rights of king will have her mentally fragmented
Lady Macbeth's vulnerability and madness is emphasised by the beginning of the play, where she speaks in iambic pentameter which denotes the character's high status

Lady Macbeth: '"Come, you spirits / That tend on mortal thoughts, unsex me here, / And fill me from the crown to the toe top-full / Of direst cruelty!"'
Lady Macbeth: '"Make thick my blood; / Stop up the access and passage to remorse, / That no compunctious visitings of nature / Shake my fell purpose, nor keep peace between / The effect and it!"'
