“What would your good be doing if there were no evil, and what would the earth look like if shadows disappeared from it? After all, shadows are cast by objects and people. There is the shadow of my sword. But there are also shadows of trees and living creatures. Would you like to denude the earth of all the trees and all the living beings in order to satisfy your fantasy of rejoicing in the naked light?”
― Mikhail Bulgakov, The Master and Margarita
