Wouldnt the ascent decompression kill the occupants anyways? Getting them up to surface isn't the saving grace to something like a battery failing. Maybe I'm missing something?

No. Subs are different from scuba. They are kept at atmospheric pressure.

For scuba, you are breathing pressurized gasses much higher than 1atm at depth, which causes decompression issues.

There's no decompression sickness on those subs. The inside is kept at a similar pressure as the surface.

the whole point of the pressure chamber is that it remained at 1 atmosphere. until it failed.
