From what movie this passage is from?

...

The old man is blind. Pete asks for water for the horses. No problem. Then the old man says he likes to listen to the Mexican radio station, even if he can’t understand the words. “I like the way Spanish sounds, don’t you?”

...

The old man invites them in for some dinner. Pete asks the old man if he lives alone. He says his son usually comes once a month with food, but he hasn’t seen him for 6 months.

Then it’s time to leave. The old man asks a favor. “Anything you want,” Pete says. The old man asks, “I wanted to ask you if you could shoot me.” Pete and Norton react. “My son ain’t coming back.” Pete says, “Oh, he’ll come back.” But the old man insists: “He told me he has cancer. He told me to go back to town with him. But I’ve always lived here.” Pete shakes his head. “We can’t do it.” The old man says, “I don’t want to offend God by killing myself. It’s a problem.” Pete concludes, “We don’t want to offend God either.” They ride off. Norton can’t help but look back toward the old man. “You’re good people,” he cries. “You need to go ahead and shoot me.”
