Eren hates Mikasa's supposed lack of free will and claims he always hated her for having no freedom. Eren points to Mikasa's headaches as proof her Ackerman bloodline is all that's keeping them together.
He does love Mikasa but is only able to confess this at the end of Attack on Titan. In chapter 139, the protagonist has a heart-to-heart with Armin, in which he expresses disappointment at the thought of Mikasa finding love with someone else after his death.
So we know Eren told Mikasa he hates her in hopes it would make it easier for her to get over him after his death, so that she could move on and be happy. But the problem is, Eren confessed his feeling to Mikasa the moment before she killed him.
Several of his friends died when the Titans invaded Trost. Then, he joined Levi's squad and felt guilty for his comrades' deaths during their battle against the Female Titan. The more friends he lost, the darker Eren's mindset became.
He was really irritated by the fact that Mikasa was being so overbearing and tried to watch over him all the time.
When Eren killed the innocent people of Liberio, Mikasa was sad, but still protected and loved Eren. Even when Eren mentally abused her until she cried, she wavered but was unable to detach herself from Eren.
Because of her grief over Eren's death, Mikasa rushes ahead of her comrades and quickly expends all of her gas, stranding herself in the middle of Trost. As two Titans close in on her, she contemplates giving up but is motivated to keep fighting by memories of Eren.
Thus, his ultimate goal is to harvest the power of the Founding Titan to sterilize all Subjects of Ymir. By rendering them infertile, there will be no further generations of Eldians, and by correlation, the ability to transform into Titan dies with them.
It's because he saw that the entire world hated him and his kind that the only solution he could arrive at was to kill the entire world. This is pretty much what convinced him that the entire world was his enemy.
The Survey Corps lost trust in Eren simply because Eren set up the Raid on Liberio knowing he was the island's biggest asset – and forced the Scouts to support his act of war by manipulating their longstanding mutually beneficial relationship in order to preserve his life.
(BOOK 1 - SEQUEL IS OUT!) Mikasa, Eren's childhood friend and the girl he believes to be the one, cheats on him, with a shady man with unknown motives. Eren then moves away and gets his own house and goes to a new high school where he gets hooks up...
She was so reckless in her pursuit of killing the Titans that she ended up using the juice in her ODM gear before accepting death with open arms.
Eren was devastated by Sasha's passing. However, because of what he experienced and what he had to do to save the Eldians, hearing Sasha's final words made sense to him and brought back memories of when they were younger, and it was easier to hate the Titans for the devastation they had caused.
Eren might not be the best at showing it, but deep down, he really does love Mikasa.
If there's one thing clear about Attack on Titan's Mikasa Ackerman, it is that she is devoted beyond all reason or logic to Eren Yaeger. For most of the story, it seems like her loyalty arises from the time he saved her when she was kidnapped as a child, but the latest plot developments imply some other force at play.
Christa is the wife of Eren.
1 Hero: He's Technically A War Hero
His offensive against the Marley convene is well-appreciated by the citizens and he's definitely gained some following. In the eyes of the Eldians of Paradis, Eren is a war hero who can keep ensuring that Paradis will win the war.
Eren's intended genocide of the human race undeniably makes him an irredeemable character -- but the Rumbling isn't the only one of Eren's sins that is wholly unforgivable. Eren has brought unimaginable suffering upon his closest friends by forcing them to kill their own comrades just to stop him.
Zeke Yeager, otherwise known as the Beast Titan or just The Beast, is the main antagonist of the Attack on Titan series.
As Armin tries to rescue Eren, the Bearded Titan closes its mouth, biting one of Eren's arms off in the process, and swallows Eren, much to Armin's hysterical horror. It is unknown how Armin survived the Bearded Titan and the others afterwards, but he was no longer attacked after the deaths of his friends.
Eren is shown to believe in freedom and have some sort of obsession with it. One of his biggest dreams is to be free and to free humanity.
Eren and the Titans
In the end of the manga, Eren attempts to destroy the world by reviving Ymir and invoking the power of the Founding Titan. However, Mikasa ultimately kills him, which results in Titans and their powers vanishing from the world.
Yes, she did end up with Jean. It's true you cannot see his face when they visit Eren's grave together but you cannot see Mikasa's face either and yet you know it is her from the scarf. In the same way, you can tell it is Jean from the hair.
I think mikasa never married to anyone. The guy standing next to her was armin, some might argue that it was jean because of his hairstyle but it's not true. Because as you can see mikasa's hair grew longer so it's natural armin grew his hair too.
In the end, she is alone by Eren's grave, remembering their childhood while waiting for Armin, Jean, and the others. Thus, if we go by confirmed information, Mikasa doesn't marry anyone.
