Major spoiler ALERT!

I think the MC just wanted to die.
The rope ends in a noose on the camera in Echo's neck. As time time move forward the noose get's tighter...
And the fact that the MC killed himself once...
Well I left with the impression that he never really wanted to be fulfilled at all. Also the camera rope around Echo's neck looks strikingly similar to the noose around the remanent's neck, so I think there's some similarity there. But if he was a death wish why would echo not just be a remanent? Idk man, I'm just excited to find out!
