Questionable ethics - Living Memory

[MikkoAkure]

We even see Otis's thoughts during the play, which means Otis thinks. He's a feeling, thinking person, and we're told by her that he's not, so we should be fine with killing him.

The real Otis died. We watched it happen. There was the Otis who was alive when he was transferred to a robot with his soul intact and there's the copy-Otis that exists in Living Memory. That if nothing else should serve as proof that the Endless are just copies of dead people. The Endless are fully aware of what they are as well, which is likely why they are able to pass peacefully. If the Endless were more like Otis and were transferred to another state while alive and continued to live, that would be one thing but the Endless died and their memories were ripped out and placed onto a server where they continued to act out "happiness" to please a pampered princess, who is also dead.

The Endless accepted they were dead when they arrived in Living Memory and accepted their disappearance at the end of the MSQ minus a few with things to finish up first before turning out the lights. Even those were fine with how it ended up.

Accepting that life is hard and death is inevitable has been a theme of this game since the theme song Answers all the way back in 1.0. Endwalker's plot was even seemingly based on the song. It is built into the DNA of the game. Accepting loss and moving on is a part of life and Sphene showed how bad it is when you can't let go, which seems to be something you share with her.

So would you say Cahciua was a sentient being to be able to do and think all that?

Never said they weren't sentient. I said they're not alive. Not the same thing. Ghosts and other undead in the game are sentient but they're not alive.
