Dig Your Own Grave

Doesn't Batman have a code against killing too?

When a character must literally dig a hole for their body, usually being forced to as the last thing they do before being killed or even Buried Alive.

One might wonder in these kinds of situations why the character just doesn't refuse to dig the grave since they're going to die anyway. Usually the reasoning is that the prisoner goes along with it because we wants to eke out as much time for his life as possible. And, at least in fiction, this is often what saves the character. Much like an elaborate Death Trap, it gives the digger time to think of an escape plan, or their allies time to save them.

As a Death Trope, Spoilers ahead may be unmarked. Beware.
