Synonym discussion
Sense: adjective/1
Cold-hearted, heartless, callous, unfeeling, and cold-blooded all describe a lack of sympathy or warmth toward others, but they differ in strength and nuance. Cold-hearted suggests a chilly emotional distance — the person is simply not moved by other people's suffering. Heartless is stronger and more direct, implying active cruelty, as if the person has no heart at all. Callous emphasizes a hardened indifference that develops over time, especially in situations where pity would be natural. Unfeeling is a more formal word that focuses on the absence of emotional response rather than active malice. Cold-blooded is the most extreme: it describes someone who deliberately plans harmful actions with no guilt or hesitation, and is frequently used in the context of violence or crime. A cold-hearted boss might ignore an employee's personal problems, while a cold-blooded killer shows no remorse whatsoever.

Etymology
Formed by combining 'cold' (from Old English cald/ceald, meaning lacking warmth) with 'hearted', the adjectival form of 'heart' (from Old English heorte). The compound emerged in English around the early 1600s as a figurative extension: just as cold temperatures lack physical warmth, a cold-hearted person lacks emotional warmth or compassion toward others.
