or eren has to die. simple as that
Ok he dies and then what a few years in the future there will be an eldian with his same ideals and will try to do the same or there will be a Marley holding grudges towards the eldians and will try to kill all eldians again and the past will keep repeating itself I don’t think there will be ever be peace because hatred it’s so deeply rooted on both parties so the only if we talking realistically is to create a new world on top of the old world
he dies with a cause. the guy's been manipulating everything that's happened; from controlling his father to possessing animals. he's basically a god now who's only goal is to (as theorized) gather all the titans, break the curse and something else happens from thereon. there'll always be yin and yang in the world because otherwise, it'd be a fallacy. you can't call a new world realistic because hatred will always grow. but that all happened because of the titans so he's paving a way to get rid of that. he probably has a second plan to protect the eldians; wipeout from the map or a barrier in their lands. everything he's done is building up to a future where his people won't suffer and his death will be the finishing touch.
Yes we all know he has to die I’m not arguing with you on that but idk if that will truly fix things I hope that he has a plan to save the eldians as you said and give them a future where the past will not be repeating and they can finally be in peace
Ok no joke here but I think that either all the eldians have to die or Eren has to succeed with his plan for the world to have peace there is no other way cuz the past will keep repeating itself and we all know this cus we can even see it in the real world there is always gonna be a person that isn’t happy with how history turn out do they’ll try to rewrite again by committing the same mistakes of the past.
