It has been claimed that an action is morally good only if it benefits another person and was performed with that intention; whereas an action that harms another person is morally bad either if such harm was intended or if reasonable forethought would have shown that the action was likely to cause harm.

Which one of the following judgments most closely confirms to the principle cited above?

(A) Pamela wrote a letter attempting to cause trouble between Edward and his friends; this action of Pamela’s was morally bad, even though the letter, in fact, had an effect directly opposite from the one intended.
(B) In order to secure a promotion, Jeffery devoted his own time to resolving a backlog of medical benefits claims; Jeffrey’s action was morally good since it alone enabled Sara’s claim to be processed in time for her to receive much-needed treatment.
(C) Intending to help her elderly neighbor by clearing his walkway after a snowstorm, Teresa inadvertently left ice on his steps; because of this exposed ice, her neighbor had a bad fall, thus showing that morally good actions can have bad consequences.
(D) Marilees, asked by a homeless man for food, gave the man her own sandwich; however, because the man tried to talk while he was eating the sandwich, it caused him to choke, and thus Marilees unintentionally performed a morally bad action.
(E) Jonathan agreed to watch his three-year-old niece while she played but, becoming engrossed in conversion, did not see her run into the street where she was hit by a bicycle; even though he intended no harm, Jonathan’s action was morally bad.

Action is morally good: benefit another person, and intention was good
Action is morally bad: harm anohter person, or the intention was harmful

Which one of the following judgments most closely confirms to the principle cited above?

(A) Pamela wrote a letter attempting to cause trouble between Edward and his friends; this action of Pamela’s was morally bad, even though the letter, in fact, had an effect directly opposite from the one intended.
- Out. Here, we only have intent, and did not have the result.

(B) In order to secure a promotion, Jeffery devoted his own time to resolving a backlog of medical benefits claims; Jeffrey’s action was morally good since it alone enabled Sara’s claim to be processed in time for her to receive much-needed treatment.
- Here we have the result, but not the intent (Jeffery did what he did for his own advantage)

(C) Intending to help her elderly neighbor by clearing his walkway after a snowstorm, Teresa inadvertently left ice on his steps; because of this exposed ice, her neighbor had a bad fall, thus showing that morally good actions can have bad consequences.
- Here, we have a morally good action: good intent (help out on own accord) and benefit another person (the elderly would not have to clear the walkway). However, because a harmful event was experienced by the elderly, it shows that morally good actions can have bad consequences.

(D) Marilees, asked by a homeless man for food, gave the man her own sandwich; however, because the man tried to talk while he was eating the sandwich, it caused him to choke, and thus Marilees unintentionally performed a morally bad action.
- No. A morally bad action must have intent. If it's accidental, then there's no intent.

(E) Jonathan agreed to watch his three-year-old niece while she played but, becoming engrossed in conversion, did not see her run into the street where she was hit by a bicycle; even though he intended no harm, Jonathan’s action was morally bad.
- A morally bad action requires both a harmful action and a harmful intent. Here, we only have an action (niece run down by bicycle) but there's not intent on Jonathan's part (he did not plan for his niece to be run down by a bicycle)

I'll take C

E, unquestionably. Jonathan agreed to watch the girl and simply didn`t fulfill his obligation.

Thanks for the explanation. OA is E.
