YMMV / Isaac Asimov's Caliban

• Moral Event Horizon: If Prospero didn't cross this in Utopia with his casual execution of Simcor Beddle's robot servants for being "willing slaves", he most certainly does when he begins gunning down his fellow New Law robots, whom he once swore to protect, simply because they were in his way. Caliban later explains to Beddle that this was why he chose to save him, an enemy, and not Prospero, an erstwhile friend: while both of them had proven themselves willing to kill sentient beings if it suited them, Beddle, at least, had never murdered his own kind.
• Nightmare Fuel: The Davirnik Gidi case in Caliban. A pathological recluse even by Spacer standards, Gidi developed an aversion, not just to human contact, but to taking any action at all for himself, a condition described as the Inertia Syndrome. Eventually he spent his entire life in a bed with feeder and waste-disposal tubes, ordering even his robots to leave until such rare occasions as he called for them, desensitized to the filthy, squalid conditions in his home, and convinced that he had achieved a perfect life. By the time one of his robots could no longer resist the impulse to check on his condition, Gidi was dead and rotting. It's even this in-universe — Gidi's house was demolished and people refuse even to speak his name because they're unwilling to face what cases like Gidi's say about Spacer society in general. Kresh himself, who was one of the officers called to the scene, has a literal nightmare about developing the syndrome himself.
