"I have come to see you, spirit of evil and lord of the shadows,' the man replied with a hostile glare at Woland.
'Well, tax-gatherer, if you've come to see me, why don't you wish me well?'
'Because I have no wish to see you well,' said the man impudently.
'Then I am afraid you will have to reconcile yourself to my good health,' retorted Woland... 'As soon as you appeared on this roof you made yourself ridiculous. It was your tone of voice. You spoke your words as though you denied the very existence of the shadows or of evil. Think, now: where would your good be if there were no evil and what would the world look like without shadow?... Shadows are also cast by trees and living things. Do you want to strip the whole globe by removing every tree and every creature to satisfy your fantasy of a bare world? You're stupid."
