The Hollywood-ized Ending

The ending isn't necessarily bad, but it's certainly a much more tame ending for audiences and I like the book's even sadder ending much better.

The book's ending:

Sarah tells Hank that she has already spent one of the bills at a convenience store, and he goes there to steal it back. In a fight with the cashier, Hank kills the man with a machete. When an elderly woman demands to be let into the store, he kills her as well. Hank flees with the bill and is never suspected.

Hank goes home and burns the money over Sarah's protests. In the epilogue, Sarah has a baby boy, whom they name Jacob. A few weeks after the birth, their daughter nearly drowns in a wading pool and suffers permanent brain damage. Hank and Sarah accept this as punishment for their crimes. Hank narrates that he pictures his brother Jacob from time to time, because only this memory makes him feel human.
