Step-by-step explanation:
In the story 'The Masque of the Red Death,' the attitude of Prince Prospero and his revelers toward those outside the abbey is one of indifference and exclusion.
They isolate themselves from the suffering and death caused by the Red Death and choose to indulge in luxurious festivities, believing that they can escape the inevitable consequences of the plague.
