Which permutation of choices did you make?
Tried to kill all of them. Missed that ugly robot at theta. Well she was lost anyway? :c
Killed Sarah and WAU. Regretted not killing Simon 2 (although I comforted myself by saying Simon 3 would somehow find him after the ARK was launched. Yeah...)
All of them: Simon-II, Sarah and WAU.
In the whole game, I "killed"/unplugged everyone I could except:
- Robin Bass (the robot near the entrance to Theta), because I didn't notice that I could unplug her;
- My little companion K8. Yes, I'm not ashamed to admit that I became attached to it.
I killed Simon-2 because I'm not one to let others suffer in silence (deleted my scan as well from earlier)
Killed the last human because she asked for it and I heed requests as such. Also because of the previous reason.
Couldn't kill the WAU because Ross antagonised me about it far too much~ his constant jump scares (only Omicron got me) made me just dislike his pestering. If Ross didn't appear and rather left instructions on how to do it, I would have considered killing the WAU for the sake of losing a hand.
I killed Simon-2 because it seemed right. Rather he die by my hand than a monsters. I killed Sarah because partly she asked for it and partly because she didn't look capable of surviving for very long. I killed the WAU because I didn't even know that it was a choice not to.
I killed everyone. This life is not worth living.
