fight fire with fire

fight fire with fire idiom
Combat an evil or negative circumstances by reacting in kind. For example, When the opposition began a smear campaign, we decided to fight fire with fire. Although ancient writers from Plato to Erasmus cautioned that one should not add fire to fire, this warning is not incorporated in the idiom, which was first recorded in Shakespeare's Coriolanus.
