The word 'callous' means someone who is unfeeling, insensitive, and indifferent to other people's suffering, usually due to repeated exposure to distressing situations. Callous is often used to describe behavior that is cold and lacking in empathy, usually when the situation warrants more compassion. For example, you can say, "his callous response to the homeless man's plea for help was shocking."
