Let me add some comments for above points:
Case 1: This is by design. We don't let the total points go below zero. But if the student has correctly answered other questions, his score will get subtracted by this negative score question.
Case 2: This is a bug. I am going to fix it in SAK-17301. We decide to take the absolute value of that field. Please let me know if this is ok with you.
Thanks,
Karen

A few Observations.
Case 1
In a case where negative marking is used for all the questions.
It seems like students never end up getting total points in negative out of an assessment even if they choose all the wrong answers. Assuming all the questions are single correct MCQ's.
Case 2.
A negative number can be specified for negative marking where it turns out that picking the wrong answer turns out to be more useful.
Suggestion: JSF validation would cover this I assume.

When authoring 'Multiple Choice (single correct)' and 'True False' questions, instructors can specify a negative point value if student selects incorrectly.
Goal: Avoid random guessing from students.
Mockups:
Authoring
-'negativeMarkingQuestion.pdf'
-'negativeMarkingPart'.pdf'
Allows instructor to specify negative point value for incorrect selection.
Delivery
-'resetSelection.pdf'
Allows students to clear radio button selection, given that they can now be penalized for guessing incorrectly.
