In the desert, there is a cave containing an inexhaustible spring. An
ancient gate exists which is impregnable, and can be latched from the
inside. This cave has been unknown for 5,000 years.
Subject A comes on the cave and enters in, drinking water from the
spring. Some time later, subject B approaches, and subject A locks the
gate. There is a reasonable probability that B will die of thirst, but
as with all probabilities we can't be certain.
Does subject A have a RIGHT to lock the gate?
Who owns the spring? A? B? A's community? B's? Both? Some third
party? No one?
What's the relation between A and B? Is A running from B, who is
trying to kill him? Is B A's dependent, who was just lagging behind?
Was the spring previously undiscovered, or is it well-known? Are there
established (legal or customary) rules regarding its use (for example,
that anyone may drink,but anyone has to wait, if a stranger is already
there, until he has drunk and left)?
Once you've cleared up those details, it might be easier to answer your
question.
