Summary

• The 100 featured heartbreaking deaths that changed the show's dynamics.
• Characters like Bellamy, Jasper, and Monty met tragic fates.
• The sacrifices and losses in The 100 shaped the characters and storyline.

The CW's post-apocalyptic sci-fi series The 100 featured a lot of loss throughout its 100 episodes, but these The 100 deaths are the saddest in the show. Because The 100 takes place during a time period when Earth is no longer fully inhabitable, the conflicts between characters were almost always a matter of survival, and death truly did lurk around every corner. The show was never one to hold back in of delivering emotional moments, and it certainly wasn't shy when it came to killing off pivotal characters starting in just the third episode of The 100. In fact, many of the deaths changed things about the show as a whole.

The characters in this series were a complex bunch, with many doing seemingly unforgivable things. Still, fans found reasons to love them, especially core characters like Clarke (Eliza Taylor), Bellamy (Bob Morley), Jasper (Devon Bostick), and Monty (Christopher Larkin). That made it so some of the deaths crushed viewers, even when they acted as completions of story arcs for the show. They were heartbreaking losses whether it was because of who they happened to, who they affected, or how they perished. New viewers still finding the series through streaming platforms like Netflix are likely to find themselves wondering, "who dies in The 100?" every few episodes as the stakes in the series are continually raised, and any character could become one of The 100 deaths.

Atom

Mercy Killed By Clarke

Atom’s death establishes Clarke as the person who will do the hard things that the other’s won’t

In the first few episodes of The 100, the show needed to establish just how dangerous Earth was despite it being inhabitable. It does that by very quickly making some big threats to the main 100 teenagers sent to Earth. A giant snake chased Octavia and Jasper in a lake and acid fog got to Atom. While Octavia and Jasper survive that encounter, Atom’s experience is different.

Bellamy, Clarke, and Charlotte come across Atom while walking through the woods. His body is in bad shape having been ravaged by the acid fog it would later be revealed is a weapon utilized by Mount Weather. Atom is in so much pain that he doesn’t ask for Clarke and the others to help him. Instead, he asks Bellamy to put him out of his misery. Bellamy, however, cannot bring himself to do it.

Atom is Clarke’s first mercy kill of the show. Only a few episodes in, and Atom’s death establishes Clarke as the person who will do the hard things that the other’s won’t. The audience might not get the chance to know Adam so well because his death takes place so early in the show, but his death fundamentally changes Clarke, and that makes it truly heartbreaking.

Wells And Charlotte

One Is Murdered And The Other Jumps Off A Cliff

It’s one of the most surprising moments in season 1 and the first real defining moment of The 100.

Technically, Wells and Charlotte die at two different times, but their deaths are tied to one another. That’s because Charlotte murders Wells, who happens to be Clarke’s best friend from the Ark. Wells actually gets himself arrested so that he ends up in detention and then, on Earth, with her. He works hard and tries to help Clarke keep the peace when the teenagers end up on Earth, but unfortunately for him, Charlotte has a deep grudge.

Charlotte is one of the youngest of the 100 sent to Earth, but she murders Wells in revenge. Not only did she end up in the Ark’s version of juvenile detention, but Jaha also made the decision to execute (or float) her parents. She wants to hurt Jaha the way he hurt her, so she takes Wells’ life.

Of course, Charlotte’s guilt also eats away at her right after it happens because the other teenagers target Murphy for Wells’ death. Because Murphy has presented himself as the biggest troublemaker, many assume he killed Wells. They also decide he should be executed for what he did, and Charlotte’s confession at the last second saves his life, but she also jumps off a cliff in front of the small group who knows the truth instead of telling everyone. It’s one of the most surprising moments in season 1 and the first real defining moment of The 100.

Finn Collins

Mercy Killed By Clarke

Though Finn Collins is an integral part of the first season of the show, but season 2, many fans no longer loved his character since he cheated on Raven with Clarke and became obsessed with her. They were not entirely sorry to see him go since his actions became drastically worse. After all, in his desire to find Clarke, he massacred over a dozen unarmed Grounders. Among The 100 deaths that are the most emotional in the show, Finn's is the least heartbreaking for the character who actually dies. Instead, it's heartbreaking for the character who has to kill him.

His death was justified in the logic of The 100's universe. Clarke stepped in and mercy-killed Finn, taking him out before he would be tortured by Grounders. It wasn't the first time Clarke had to kill one of The 100 in an act of mercy, but it did mark the first time that Clarke had to end an ally's life who wasn't yet even injured, seemingly ending her innocence and putting her on the path to become Wanheda.

Miles Shaw

Radiation Barrier

Miles Shaw doesn't initially make a big impression as he's the pilot of the prison ship that was in cryosleep before the world ended (again). The primary reason the audience grows to care so much for him is because of how much Raven cares for him. Raven becomes the moral center of the show as it goes on, so when she cares for someone, it's impossible not to sympathize with the character.

Shaw survives the end of the world to help what's left of humanity enter cryosleep and makes it to the other side of the galaxy to a new planet. He dies thanks to an unfortunate mistake as a radiation-fueled barrier kills him before it can be disabled. Raven finally seemed like she might have someone good in her life, which she deserved, but he was taken from her in one of the most unfortunate The 100 deaths.

Luna kom Flokru

Killed In Conclave

A Nightblood introduced late in The 100 after all of the others are murdered, Luna is a surprising candidate for Heda. She's an incredibly well-trained fighter and leader, but she wants nothing to do with the violence that persists in Grounder culture. That all changes when her entire clan suffers from radiation poisoning while she survives because of being a Nightblood.

Luna takes it upon herself to enter the Conclave to fight for the bunker that could save the last of humanity. The difference is, she doesn't want anyone to have it because she doesn't think they deserve to survive anymore. Luna goes all out in the Conclave, defeating several enemies before she's ultimately killed as well. Her death is largely so sad among The 100 deaths because of how far her character turns from her peaceful nature.

Marcus Kane

Floated By Indra

The tale of Marcus Kane is actually a pretty sad one out of all of The 100 characters who manage to survive through most of the series. He starts the show as someone who is all about the "greater good," willing to sacrifice a few people to save the rest of the population. He grows into someone the audience trusts and loves, so his ing hurts.

On his deathbed, Abby had him reborn using the Mind Drive in the body of a younger man named Gavin. Of course, Kane never wanted that and chooses to die rather than live that way. He opts to be floated by Indra and Abby's reaction makes it much harder to deal with. Abby sacrifices and researches trying to find a way to save him, and when she finally finds one that allows him to live, it's not what he wants.

Monty Green & Harper McIntyre

Died Of Old Age

Though Monty and Harper are obviously two different deaths, the couple died together and count as one. Monty Green was arguably The 100's only true good guy, always trying to do what was right and be better. His romance with Harper McIntyre was one that fans adored. At the end of season five, everyone went into cryosleep and these two were meant to stay up a bit longer, so Monty could figure out the next move. That's not exactly what ends up happening.

Clarke and Bellamy are awoken over a century later and shown a video detailing how the couple never went to sleep. They lived out their lives until old age together and had a son, before ultimately coming up with the plan to save them all. It was a beautiful ending but also a sad one for two of the show's best people. Their choice is a noble one, but heartbreaking because it means the show goes on without them.

Charmaine Diyoza

Crystallized by Gen-9

When Charmaine Diyoza first appeared on The 100, nobody would've believed they'd be sad about her death. She was a terrorist and the antagonist for a lot of season 6. Initially, her goal is to be the one in control of the only fertile valley left on Earth because she wants a place to raise her unborn child. She eventually understands that all of the fighting between herself and the criminals with her only ends up bringing more harm than good. Ultimately, she goes on to form a bond with Octavia Blake that turns her around as a character.

She becomes much more likable in The 100 season 7 when she gets to meet her grown-up daughter Hope. So, it hurt badly to see Diyoza sacrifice herself in one of the most selfless The 100 deaths to save Hope and her friends. She is crystallized by Gen-9 and Hope can do nothing to save her, watching in complete sadness.

Jasper Jordan

Poisons Himself

Jasper is mostly the comic relief in seasons 1 and 2 of The 100. As one of the most beloved of the original 100 teens dropped on Earth, when Jasper dies in The 100 season 4, it's truly heartbreaking. Jasper's death in the series comes just as the main characters discover that the world is about to end - again. Following the death of the inhabitants of Mount Weather in season 2, Jasper struggles to deal with his grief at losing Maya, and the part he played in all of those lives lost.

Jasper isn't the only member of the original 100 to choose that path

When Jasper finds out that the world is about to end, he doesn't see the point of struggling against another apocalyptic event, especially when he also discovers that his skills aren't considered "worthy" of being one of the last of humanity. Jasper isn't on the list of people the leaders want to save. He chooses how he wants to spend his final days, partying with friends, and finally, using poison to end his life. Jasper isn't the only member of the original 100 to choose that, but he's the most prominent, and it's a heartbreaking conclusion to the character's story.

Maya Vie

Killed By Radiation

Initially, fans did not love Maya. They believed that she was faking some of her feelings for Jasper and agreed with the folks at Mount Weather for most of her tenure. That's proven not to be the case, however, when she helps the of the 100 captured and held at Mount Weather as much as she can.

Maya's death in The 100 marks a huge turning point for the show. She is killed along with the rest of Mount Weather when Clarke and Bellamy flush radiation through the facility with the help of Monty. It is sad to see her die but also crushing to know what it does to Jasper. He becomes incredibly depressed, unable to understand the violence his friends perpetuate, and that eventually sends him down the path of taking his own life.
