I guess it doesn’t matter, but it is the simplest way to look at the situation and so most useful. I would say it’s the most accurate for your consequentialist approach: certain binary actions lead to certain binary consequences.

In this case the binary action is getting in the sub or not. The outcome is dying or not. There is no analogue aspect of either. You can’t half enter a submarine or half die.

Decomposing things down to a binary is fundamentally how things work. We can analyse things to death and add our own mental/idealistic layers of continuity (like probabilities of outcomes or degrees of truthiness of statements), but the decisions that come from the analysis are always binary.
