This story from C.S.Lewis’ The Great Divorce is one of my favorites:
A mighty angel approached the man and asked, “Would you like me to make the lizard quiet?”
“Of course I would,” said the Ghost.
“Then I will kill him,” said the Angel, taking a step forward.
“Oh—ah—look out! You’re burning me. Keep away,” said the Ghost, retreating.
“Don’t you want him killed?”
“You didn’t say anything about killing him at first. I hardly meant to bother you with anything so drastic as that.”
“It’s the only way,” said the Angel …. “Shall I kill it?”
