You could just kill the guard by leaving them in the bag
I would immediately shift your alignment to chaotic evil for it because you’re literally making them suffocate to death over a period of about ten minutes, but it’s still RAW.
Except if the guard manages to rip a hole in the bag from the inside, they can destroy the bag and everything inside it will get scattered across the Astral Plane. Pretty bad for the guard, but better than a slow death being suffocated. Plus you don’t need to eat or breathe on the Astral, so they could live there indefinitely.

Tearing the bag from the inside seems like an easier said than done proposition.
Bag of holding around the head. Tear it.
Faster in theory but I’d be incredibly tempted to have it create an astral plane flavored headless horseman enemy
Oh damn that’s good
Bodyless floater in this case, as the body is on the Prime Material plane.
