As part of the backstory in the 1992 movie "Unforgiven," an outbreak of smallpox hits the entire country, killing Munny’s wife Claudia. He deeply loved her. She had tamed his whiskey-drinking, gun slinging ways. Her death leaves him having to raise two children on a hardscrabble farm where the animals are now sick.

What will he do? Does he have any options on how he should live his life?

“William Munny (Clint Eastwood) was once, we learn, a gunfighter, and not a very nice one. He killed not simply bad guys, but also women and children, and he didn’t feel very good about that. Now he is trying to support his motherless family by working as a hog farmer. When the word comes of a $1,000 bounty on the heads of two cowboys who have carved up a prostitute, he accepts the challenge. He needs the money, and perhaps he is attracted to his old ways. The prostitute was attacked in Big Whiskey, Wyoming, a town ruled by Little Bill Daggett (Gene Hackman), a sheriff who mirrors Munny’s own ambiguity about violence and domesticity.

With "Unforgiven," it is not simply about its plot. It's not just about whether William Munny collects the bounty, or about who gets killed in the process. It is truly also about what it means to kill somebody, and how a society is affected when people get killed. Self interest and morality are played out throughout this entire picture.
