What is related to 'Sympathy' in the same way as 'Virtue' is related to 'Vice'?

Concept: In a word-pair analogy, first identify the LOGICAL RELATION inside the given pair, then reproduce that exact relation on the new word. Here the relation in Virtue : Vice is ANTONYMY — a virtue is a morally good quality and a vice is its moral opposite. So the task reduces to: find the word that is the OPPOSITE of Sympathy.

Application: Sympathy is the feeling of pity, compassion or fellow-feeling for another's suffering. Its direct opposite is the disposition to be indifferent to — or to enjoy — another's suffering, which is exactly Cruelty. Therefore Cruelty completes the analogy: Virtue : Vice :: Sympathy : Cruelty (good↔bad opposites in both pairs).

Contrast: Compare the other choices against the required ANTONYM test:

• Kindness — a near-synonym of Sympathy, not its opposite, so it breaks the good↔bad pattern.

• Emotion — a broader category that Sympathy belongs to (a part–whole link), not an antonym.

• Charity — an associated benevolent act, again on the same positive side rather than the opposite side.

Cross-check: Only the opposite-meaning word mirrors Virtue → Vice; substituting any positive or category word fails the antonym relation. Hence Cruelty is the answer.
