What is another word for heartlessly?
Pronunciation: [hˈɑːtləslɪ] (IPA) 
When expressing a lack of empathy or cruelty, heartlessly can sometimes seem too harsh a word to use. Fortunately, there are several synonyms available to temper the tone. Callously and coldly both convey a sense of detachment or disregard for others. Ruthlessly suggests a specific type of cruelty, often in pursuit of one's goals. Pitilessly and mercilessly both emphasize a lack of sympathy or compassion, the former being slightly more archaic in tone. If a more indirect phrasing is preferred, one could use unfeelingly or unemotionally to express a lack of emotional involvement. Regardless of the choice, each synonym paints a picture of a lack of heart.
