There are many questions, how will he be able to survive after all these events? Here, the character of Eren began to develop into one of the greatest characters in the anime world. Let's start by mentioning the factors that affected his personality and the most important events that led to radical changes in his personality. So let's get started now...burn down



(1) And for the most important event that led to the change of his personality
(the first episode): the death of his mother
The event began with the Smiling Giant attacking Irene's house and his mother lying on the ground above the wreckage, and Irene clinging to the hope that he would save her from that suffering. But what will he be able to do as a child? Simply nothing! He felt powerless and weak. And Hannes came with the maneuvering equipment that he had only used during his military training days, facing for the first time a real giant. He let Carla die and carried Eren and Mikasa with him to take them to safety. Eren sees with his own eyes his mother being devoured by a giant. What a sight that will remain in the minds. Here he began his first goal of wiping out all the giants from this cursed world. And he decided to join the reconnaissance squad to achieve his first goal towards achieving his dream. Feeling: Here, Eren has seen the truth of the world hidden behind a large curtain. He saw the giants as if he was living in a lie invented by people saying: the giants will never be able to break the wall. But now the opposite of what they said has happened, so what is their justification now? Fear, heartbreak, weakness, hate, malice, revenge, trauma, betrayal. All those feelings he felt in one day.

The inevitable death is what happens to everyone who dares to confront the giants. But Erin was always out of the ordinary. He went straight for revenge  for his friend who hadl of the giant. But what happened is that because of his haste and anger, he was also eaten. At this moment, we thought the series had ended, as Eren had died! But are there still episodes to come?
