“"Dix," Case said, "I wanna have a look at an AI in Berne. Can you think of any reason not to?"
"Not unless you got a morbid fear of death, no."”

“Look right at it. Know you can." Dad said. "Look right at that fear. Fear is the biggest bullshitter.”

“I don't remember Moses writing, 'Thou shalt not kill.. unless you think you have a good reason.”

““I think you look on death as your friend,” she murmured. “That is a strange friend for a young man to have.”
“The only faithful friend in this world,” he said. “Death is always sure to be at your side.””

““Every creature has fear,” Jared said. “Even the non-conscious ones.”
