“Granny Weatherwax was often angry. She considered it one of her strong points. Genuine anger was one of the world's greatest creative forces. But you had to learn how to control it. That didn't mean you let it trickle away. It meant you dammed it, carefully, let it develop a working head, let it drown whole valleys of the mind and then, just when the whole structure was about to collapse, opened a tiny pipeline at the base and let the iron-hard stream of wrath power the turbines of revenge.”
― Terry Pratchett, Wyrd Sisters

“Then the glow grew brighter: a holographic golden sickle with a few sheaves of wheat, rotating just above Meg McCaffrey.

“There is nothing worse than having an enemy who is a total loser. It's incredibly frustrating when seeking revenge against one, because you come to the realization that there is really nothing you can do to make the person's life worse than it already is. They have nothing to take, there is no way to screw them over if you have been their victim. It's maddening.”
― Ashly Lorenzana

“Harry was left to ponder in silence the depths to which girls would sink to get revenge.”
― J.K. Rowling, Harry Potter and the Half-Blood Prince
