The Narrator's perspective only gets more horrifying the longer you think about it. Like, imagine being an Echo of yourself—one of many, all made to serve a very particular purpose and knowingly living on borrowed time, if 'living' is even the right word for your current state of pseudo-existence.
You've inherited the mission of a dead man—it's literally the only thing left that you can do before fading, so you sure as hell better believe in it; the alternative would be unbearable. Only you keep failing. With every loop that you don't remember, your lack of agency in this situation becomes starker—you can influence small things, sure, but it becomes increasingly clear that you have no real power, no matter how personally invested you are in the events unfolding in front of you. You are, after all, only an Echo. You've forfeited the right to meaningfully engage with the world.
Worse—every loop you're made aware of is another time you've failed, with unimaginable consequences, though you had no control over these previous iterations of yourself and can't even learn from their mistakes. Everyone around you is operating on a shared perception of reality that you are not part of, will never be part of. After a few repetitions, you are, ironically, the least informed person in the room. All you have left to go on is an evidently outdated script. At the same time, everyone else is experiencing a contiguous version of you, comprised of parts that are, in some sense, also you, while at the same time existing at a complete remove from your current perception of self. Whatever you don't know you did—that's you now. You are, after all, only an Echo. You've forfeited the right to define your own identity, never mind know what it is.
Even worse—this has trapped you within a stagnant hell of your own creation. Nothing you say or do really matters in terms of your own self (the rest of the world is a separate issue entirely). Anything you've come to believe—say, for totally hypothetical example, that you were wrong actually and your envisioned paradise is really a hell beyond any you had the capacity to envision—has about as much permanence as a drawing in the sand. 'You' will continue, exactly as you were, no matter how much you might like to change your behavior. Every possible future has already been set in stone. You are, after all, only an Echo. You've forfeited the right to say anything you haven't already said.
For some reason, no part of any of this has made you feel more comfortable and at peace with the general concept of finality.
The really, truly absolute worst part, though?
There is no one for you to blame but yourself. And that's exactly what turns your story into such a tragedy.
