What if eren saw the conversation between gricha and frida in the arc of historia in season 3 part 1

Asked by Eren yeager, what would happen if Eren saw the conversation between Gricha and Frida in the story arc in season 3, part 1? And also see his futuristic self, I mean the moment in which history and his father touch him in season 3 part 1 I mean, what would happen if at that time he saw how he himself told his father to kill the family history ? Because when the two touched him, he didn't see it complete. But at this point in history it will be different.

It all starts when Rod and his daughter touch Eren's back, Eren then sees his father's memories. Grisha, who went to the Reiss asking that, as Queen of the Eldians, exterminate the Titans, to do it for his wife and son, Frieda, went from having green eyes to having purple eyes and said NO. Grisha pulls out a knife ready to transform, but it didn't transform, he dropped the knife, The Reiss were running away less Frieda who was about to bite. Grisha exclaims, "I am a doctor, I do not kill people, I save people" When Eren's ghost of the future tells him, what are you doing cowardly ?, Grisha knowing that his future son would respond to himself that the titan attack has The super ability to see the future and he saw himself killing the Reiss and empowering Eren. Eren's ghost of the future would tell him to remember Fay and his fellow revolutionaries. Grisha, remembering why he arrived, became a Titan and ate Frieda, then killed the Reiss, letting Rod go on purpose. After leaving his titan he would ask forgiveness of the ghost of Zeke of the future for being a bad father telling him that he saw the future and Eren will be the perdition of the world and must stop him. They were awake. things happen in a similar way when Kenny removes the thing from Eren's mouth. If Eren knew the truth at that moment, he would simply become a titan after knowing that he would simply become a titan. Rod Reiss's daughter in reaction would become mega colossal titan. killing Rod and everyone present, except Eren who would be crushed between the rocks and with no one to give him the serum, Levi, Mikasa, and the others would die, surviving Armin and hange that were outside the cave, with explosives in their mouths , They kill Rod's daughter who had become a titan, Darius Zackey is appointed governor, Eren is shown with constant stress caused by knowing that in the future he would become bad and with his simple action and having killed several loved ones , not having been able to save neither Mikasa nor history, Then it would be time to go to shinganchina, similarly occurring the first part, Only that without Levi, surver corps that faced the beast titan would die completely. And without Mikasa, jean, Connie or Sasha, they wouldn't have defeated the titan armor when he got up so Eren could have defeated the colossal titan, Armin dying in the process since they wouldn't have Kenny's serum, but Reiner would take advantage of Eren being fresh out of his titan to capture him and they would have defeated him, after that battle. Zeke would order to return without Annie to Marley, on the boat trip, Zeke dialogues with Eren. Eren recognizes him from the memory and says, "You are Zeke", Zeke is surprised, Wow, I see you recognize me, Brother. Eren is angry that the prophecy was real. He asks the truth and Zeke tells him his version of the facts, upon arriving at Marley, The warriors present Eren as the founding titan, and Marley's kings prepare him to be eaten by one of them, Eren becomes the one who understands Zeke, it seems that the brothers had become friends, Zeke tells Eren the Euthanasia plan and the day Eren was supposedly eaten, Zeke sneaks into his prison and touches him, entering the 2 brothers to the invisible roads, Only that Zeke is chained by the will of Karl Fritz. Eren takes advantage of that, to enter his memories and cause his own tragedy, Leaving his Memory Zeke can do nothing because he is chained, remember that in the original story Zeke let go of the chains because he spent months on the invisible roads in which Eren was regenerating. So Eren uses Ymir Fritz to cause the rumbling of the earth, and giving a warning to all the Eldians of the world, After that, the Tibur Family comes down to eat Eren, but Eren tells them that eating it will not fix anything, He entered the invisible roads and convinced Ymir Fritz not to obey anyone besides him, so unless they do what he asks, the rumbling of the earth will not stop, while on the walls, they have recovered shinganchina fruit of the battle, returning flosh as the sole survivor, after days destroying basements in each house he found the basement of Eren's house and the newspapers giving the truth, when the truth was discovered. and when Eren gave the warning he panicked and Annie came out of her glass, Weakly walking, That way once the future is seen, the future is inevitable On the roads are options, what will happen in the next part?
