Does patrolling with 0 unrest kill population too?

If you're in a castle, there are many times you don't want to patrol since that army is no longer safe. If there's no fortress and no unrest I don't think there's any reason to pick defend over patrol, though.

Actually, if there is *no* fortress I sometimes defend instead of patrol in later game situations simply because I will find that commander with "n" again, and he might just get lost and forgotten without it.
