Maria

• The devil puritan that he is 


  (2.3.)

  Maria's passionate hate for Malvolio.

  Flows out of her - pent up.

  Religiously motivated - would have been supported by Elizabethan audience
• that it is his ground of faith that all that look on him love him


  (2.3.)

  Malvolio's arrogance.

  Ironic as this is why the gulling plays out.
