Issue: I simply refuse to use the stun gun on any robot in Delta

If you want to make the choice easier:

Spoiler below!

we know that the smaller & cuter & more helpful robot isn't actually sentient (i.e. a human-robot) but rather a full AI that doesn't have a consciousness. As such, destroying it isn't really killing anything but rather more like taking apart a computer to use some of its component parts.

To be immersed in the world is to take a choice, though. The fact that you can step back and not make a choice is an immediate breaking of the fourth wall, removing yourself from Simon's virtual dilemma. Simon doesn't like this any more than you do and he says so. Going on is the only option for him though.

That's not exactly true. Granted, the documents in HQ on Delta state that, but there is a lot of thing different in the world of SOMA. Omnitool had a basic AI setup too yet later you made this toaster talk and think. Who knows how the little helper was altered.

Also, I spent few hours looking for the spare chip anywhere, abused the hell out of the jumping glitch and there was literally nothing.
