>>219977736Even if thats true(which it probably isn't) Eren had no way of knowing this since he gets no future memories after he dies
All of his friends could have been gunned down immediately after he died for all he knew.
My main gripe though is that he can control any titan at any point of time (so every death in the entire manga could've been prevented/might've been orchestrated by him) so every scene in the manga is retroactively meaningless
