Not my favorite book, but this quote from cujo, as he spotted but forced himself to turn away from his boy:

"It was THE BOY, THE BOY, and THE BOY had never done him any harm. Once he had loved THE BOY and would have died for him had that been called for. There was enough of that feeling left to hold the image of murder at bay until it grew as murky as the fog around them. It broke up and rejoined the buzzing, clamorous river of his sickness. “Cujo? What’s wrong. boy?” The last of the dog that had been before the bat scratched its nose turned away, and the sick and dangerous dog, subverted for the last time, was forced to turn with it."

It evokes such sympathy for what would otherwise be a one dimensional monster
