In theAttack on Titanseries, Eren was one of the most formidable forces depicted in the series thanks to his astute mind and ability to transform into the Attack Titan. Eren possessed a lot of authority and responsibility, but his choices often led to the murder of many innocents and trusted allies. As more and more characters met their ends as a result of Eren’s deeds, viewers began to question whether or not these deaths were genuinely unavoidable, or whether they were instead all a part of Eren’s master plan.

The Smiling Titancruelly devoured Eren’s mother, Carla Yeager, in the first episode of theAttack on Titananime series, and viewers naturally believed that he was powerless to stop it. Now that they know that the Attack Titan can see into the future, it is clear that Eren was responsible for his mother’s death and most of what happened in the series.

In chapter 139 of theAttack on Titanmanga, Eren tells Armin that he brought the Smiling Titan to his house, where she was killed. After Bertholt had an encounter with the Smiling Titan during the Fall of Wall Maria, this was done to keep him alive, so he might eventually transferthe Colossal Titan’s powers to Armin. So, Eren had the opportunity to prevent his mother’s tragic death, but he chose not to to protect Bertholt.

3Citizens Who Died During The Assault On Stohess

During the Assault on Stohess, Eren Yeager and the other scouts found out that Titans were hiding inside the walls of Stohess. This was a big deal. The Assault on Stohess was a major turning point in theAttack on Titanseries because of this. It was revealed thatAnne Leonhart, the Female Titan, had assumed her titan form. Armin’s initial misunderstanding led to the chain of events, in which he believed Annie to be the Female Titan and himself to bethe Attack Titan. In spite of Eren’s protests, Captain Erwin Smith came up with a plan after accepting Armin’s deduction.

When Eren found out who Annie was, the two of them got into a battle with each other. Near the end of the conflict, around a hundred lives that may have been saved were lost as a result of the fighting. Eren, the protagonist of the series, had the ability to stop the plan from being carried out by making a public appeal for everyone to leave the area immediately. This is not totally out of the question, considering that numerous shonen anime episodes illustrate the importance of showing respect for human life when confronting a formidable foe.

2The People Of Marley

The Eldians formerly conquered Marley; however, during the Great Titan War, the Marleyans rose against the Eldians and subdued most of their area withthe numerous Titan warriorsin their warrior unit. To keepthe Eldians captive on Paradis Island, the Marleyans surrounded them with Titans. Following the premeditated assault of Wall Maria, the surrounding Titans blindly ate and invaded Eldian territory. This would eventually trigger Eren Yeager’s desire to protect his friends and family from the grips of the Marleyans and the mindless Titans.

The conflict between the Eldians and the Marleyans is depicted in the anime series. Eren Yeager, the series' protagonist, was of Eldian descent and aspired to liberate the Eldians from Marleyan control. Following many ups and downs in his life, Eren resolved to launch a surprise attack on the Marleyans in order to prevent them from attacking the Eldians first, as well as to get retribution for the havoc and misery they had caused. Eren’s strike on Marley was deadly, killing many innocent people.

As the series' protagonist and ‘hero,’ many viewers questioned Eren’s decision. They wondered if he might have maybe rescued the people of Marley by not extending the cycle of warfare between the two countries, or by orchestrating his intentions without endangering innocent lives instead of bringing them damage, despite the fact that his attack was portrayed as a necessary evil.

1The Eldians That Ingested Zeke Yeager’s Spinal Fluid

Eren’s half-brother,Zeke Yeager, possessed the power of the Beast Titan and could transform others into Titans if they consumed his spinal fluid. To that end, Zeke had his supporters,the Yeagerists, blend his spinal fluid with Marleyan wine, which was offered as a gift to the Eldian Military, so he could transform them into Titans with an activation scream when the time was right.

Once Zeke activated the Titan metamorphosis of many Eldian military soldiers, chaos erupted, and many lives were lost, despite the fact that the tragedy could have been avoided. Eren was working closely with his brother at the time and could have been aware of his brother’s intentions. If he hadn’t, it wouldn’t have taken him long to find out if he had enquired, but he was too preoccupied with vengeance at the time. Many viewers believe Eren was aware of Zeke’s plot but saw the countless deaths as necessary to achieve the future he had glimpsed and desired.
