Dawntrail's MSQ story is a disaster and waste of potential. [full spoilers]

[Lersayil]

We didn't delete any kid or anyone at the end. The Endless does not even have a soul which has already be tripped from the memory. The memory is not even authentic but already heavily modified to suit the agenda of the creators. Even Sphene wasn't real, it was implied several time the real Sphene wouldn't go to the extreme, her current self is basically just a brainwashed version that's programmed to protect the Endless at any cost. She's just an agent to execute the will of the AI core. The Endless zone was just a simulation, nothing more, nothing that can even remotely imply any sort of moral implication whatsoever. The system is basically just a self-serving AI trying to stay in existence while using real human as fuel.

S9 and the ourskirt are real people. Some argument can be made if the Endless still retain their soul, but as it is they're just data.

See, this is why I think they didn't make things clear. They've written themselves into a corner. If they were real, we just committed genocide (justified or not). If they weren't, then like 80% of the emotional string pulling in the last zone was completely empty and meaningless, and we'd be a lot less (if at all) sympathetic towards Sphene and the Endless. And we couldn't have that now can we?

They wanted the proverbial cake, and eat it too.
