Something I particularly appreciate is that in most of these stories, the recipient of mercy has genuinely done something horrid. Showing mercy and compassion to a dying, destitute Fantine is absolutely laudable, but it's much, much harder to show mercy to the kid who just blew up your entire planet.
Captain America: Civil War (2016). Since this one just came out, I don't want to say too much for fear of spoilers. Suffice it to say that a character embraces forgiveness over vengeance in a way that feels fully earned, without any of the weird macho "I forgive you and the horse you came in on" posturing of a lot of other movies. What's more, because we love both Cap and Iron Man, we genuinely want to see them reconciled rather than watching them pound each other to a bloody pulp. It's a lovely thing when a movie makes you wholeheartedly root for mercy rather than appealing to that nasty bloodthirsty part of your heart that just wants to see the bad guy die in a thousand horrific ways. Even if we think that either Cap or Iron Man is dangerously wrong, we can't help empathizing with them both.
X-Men: Days of Future Past (2014). On the one hand, I kind of wish this movie had embraced mercy for its own sake rather than taking the approach of "if we let Mystique assassinate this horrible person, the world will become a nightmarish dystopia." On the other hand, I get that a multi-million dollar summer blockbuster needs epic stakes, and "prevent the world from becoming a nightmarish dystopia" is easier to sell than "save Mystique's soul." Even taking the movie on its own terms, it's a far more interesting story to save the word by sparing the life of a truly odious human being than by rescuing a saintly Professor X type (or, heaven forbid, yet another story where they save the world by blowing up a doomsday device). It may not be all the way to loving your enemy and praying for those who persecute you, but it's darn close, and that's a rare thing.
Les Miserables (2012). The list of merciful films that kicked off these blog posts had the 1935 version of Les Miz, but the musical is always going to have a special place in my heart, and this is, after all, about recent movies. (The 2012 adaptation is especially welcome in light of the 1998 abomination that ends with Valjean witnessing Javert's suicide and skipping away with a huge smile on his face.) The Bishop of Digne's mercy toward a Valjean who certainly didn't deserve it at that point, Valjean showing compassion and love to Fantine and Cosette rather than looking the other way, Valjean saving a stranger from imprisonment and condemnation at the expense of the life he's made for himself, an antagonist who is essentially the personification of justice without mercy--they all combine to make one of the most stirring testaments to mercy that I've ever seen.
The Phantom of the Opera (2004). At its heart, Phantom is Gothic horror, and Gothic horror loves heroines whose mercy can get through to a monster. (See also Mina Harker; her redemption of Renfield is one of my favorite parts of the novel, and it sadly tends to get passed over in adaptation.) The Phantom doesn't let Christine and Raoul go because Raoul beats him in a duel or because Christine screams at him until he realizes that she will never love him, but because Christine shows him love and compassion for the first time in his life--and that makes him realize how wrong it is to imprison her.
Of course, one could point out that Gothic stories should have allowed women to kick butt as well as being merciful saints. This is absolutely true--but it's a two-way street, and I'd like to see more men being merciful saints in addition to kicking butt.
(Side bar: I'm going with the 2004 version because it meets the criterion of "wide-release movie," not because I'm trying to make a statement about whether it, the 2011 live version, or the original cast recording is better.)
I'm casting the net on merciful spec fic stories to include classics as well as recent fare, because otherwise this list is going to be embarrassingly short. Either mercy is rare as a major component in spec fic (which would surprise me, since literature can take more risks than wide-release movies can) or I've been reading the wrong books.
"The Other Foot" by Ray Bradbury. Ray Bradbury's fiction runs the gamut from joy to whimsy to melancholia to horror, so it's no surprise that mercy works its way in there, too. His final novel, Farewell Summer, had a reconciliation between the town's rambunctious trouble-making boys and the crotchety old man, but I unfortunately can't remember any details. Everything about the end of that story is eclipsed in my memory by the scene where the old man and the lead boy have heartfelt conversations with their penises (no, really).
But the theme of mercy comes through most starkly in "The Other Foot," one of the few beams of light in the almost oppressively dark anthology The Illustrated Man. An all-black colony on Mars discovers that white settlers are coming, and the colonists are prepared to get revenge by instituting some reverse Jim Crow laws--until they discover that Earth has been destroyed in a nuclear holocaust and the lynching trees have burned to ash. There are racially problematic elements in this story, to be sure; as this essay points out, there are issues with the feel-good white wish fulfillment stories of black people "transcending" the wrongs done to them and forgiving white people willy-nilly. But Bradbury has also written lesser-known stories that refuse to let white people off the hook. If you're interested in reading some of these stories, check out his realistic fiction anthology The Cat's Pajamas. In addition a downright vicious revenge story about a white man who rapes and murders a black woman and draws the wrath of some local carnies, it features a story about a cold-hearted white man with no regard for the black housekeeper who essentially raised him; Bradbury admits in the anthology's introduction that this character represents his own worst fears about how he'd treat his housekeeper if he met her again. Taken in light of Bradbury's other stories, "The Other Foot" is a plea for mercy that he's not entirely certain any white person, including himself, deserves.
Ender's Game by Orson Scott Card. Up until the last chapter, Ender's Game is a bizarre non-example. It's one of the only works I can think of in any medium that starts out by embracing empathy without compassion--Ender completely loves and understands his enemies so he can crush them into the dust. (Yes, he thinks killing the buggers is a game. That doesn't change what he does to Stilson and Bonso.) Like its opposite, the compassion without empathy that we see in "poverty porn," this has little to do with genuine mercy. In the end, however, we get to see Ender using his love and empathy to save lives rather than end them, and the buggers show mercy and forgiveness to him as well.
Although I'm talking about adult media here, I have to give an honorable mention to Before I Fall by Lauren Oliver. YA books tend to bring in mercy as a major theme, in part because their target audience is in the process of learning that there are few card-carrying villains in the world. Before I Fall, a cross between Mean Girls and Groundhog Day, is my favorite example of this. Popular, bitchy Sam Kingston enters a repeating time loop that causes her to reevaluate the way she treats her family, her teachers, and her peers. Too often, when we see the "mean kid learns not to be mean" character arc, it ends with the protagonist going from one kind of bully to another; instead of taunting and humiliating nerds, she taunts and humiliates her shallow former friends. Before I Fall doesn't shy away from how unconscionably cruel Sam and her friends can be, but it also constantly reminds us that they're acting out on very real pain of their own. In fact, the loops that make her feel worst about herself are the ones where she lashes out at her catty best friend or jerk boyfriend in ways that would have been played as stand-up-and-cheer moments in lesser books. Sam's growth isn't complete until she learns to show mercy to all her peers, no matter how undeserving.
