People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone, do it in such a way that you do not have to fear their vengeance.
At long last it ended. Halaster Blackcloak lay panting and drenched with sweat. He stared up into dusty darkness.The rags of his shredded robes clung to him.
"Revenge" he announced calmly, as he forced his last shudders into oblivion,"will now commence."
He did not, however, move for a long time, even when the cold made him shiver. He lay still, remembering every last detail of Nergal's movements, words, and reactions, the archdevil's precise appearance... and what spells would make the best weapons against such a one.
Just as patiently, he recalled the drawbacks and precise effects of each suitable spell and his best tactics for using them in Avernus. At length, he smiled coldly and told the darkness, "It seems Halaster Blackcloak would make a good devil himself."

When I began, my Charmander was level five
Fighting in grass, I hardly made it out alive
Pidgey hurt me with Gust and Sand-Attack
His Fire Blast is going to roast all of you
"Cros Treewind, your ass is mine!"
— An EverQuest fan comic with the caption that "Revenge is a dish best served 40 levels later."
Sergei:Perhaps it was the haste of a man who longed to take his revenge like is vodka, in one dreadful swallow. But I see now I must take my time. I will plant seeds of revenge and let them grow. Then I'll harvest the vegetables of revenge. And from those vegetables, I will plant more seeds.
Stan: And then you'll get your revenge?
Sergei:No, Smith. From the third or perhaps fourth harvest renge-plants, I will make a vegetable stew, and season it perfectly. With revenge!
Sarda: I made you what you are today so you'd know exactly how insignificant you are when all that power fails to stop me from killing you.
Black Mage: That's messed up, Sarda.
Sarda: Oh? The thought of it kept me warm for billions of years.
You see, it's the slow knife, the knife that takes its time, the knife that waits years without forgetting, then slips quietly between the bones. That's the knife that cuts deepest.

Devon: You know, revenge is a dish best served cold. Like sashimi or pizza.
Jack: You prefer cold pizza?
Devon: The morning after? It's the best.
Jack: Better than hot pizza? That's insane.
Devon: You don't tell me what kind of pizza to like! You don't tell me anything anymore, Jack!
