There are a plethora of synonyms in the English language for the phrase "with scarce sympathy." One could use words like "unsympathetically," "indifferently," or "callously" to convey a lack of empathy or concern for a situation or person. Other options include "heartlessly," "coldly," or "cruelly," which all suggest apathy or even hostility towards someone's plight. Yet, it is important to note that synonyms can only convey so much meaning; ultimately, it is the context in which they are used that determines their precise implication. Regardless, one thing is certain: when someone is acting with scarce sympathy, they are not exactly endearing themselves to others.
