Finally in my position.
Spoiler ahead - Ending E in my opinion
Edit: Ending E would lead me (and or the reader) to believe that the character we're playing as is just a Test subject of some sort, on a spaceship floating off to who knows, which adds another conundrum, because if there are already people out there, (the dead bodies) that would mean that the character was either not the only person who escaped, or the dead people in ending E were people who refused to get into the Pod, but since there's still electricity that means that the Earth in that universe is most likely "burning," in a way, where humanity had to move to space just to not become extinct, and since their's mold/algae on the ground, it makes me conclude that ending E is the player realizing they were in a simulation, with the only thing to look forward to is death, meaning that the friendly fire is basically a firewall ironically enough, so that would mean that you bribed the firewall somehow? I don't know man, I'm just a normal dude. I'll probably do some more inspection on ending E.
