Humanity is an attribute that represents compassion, love and kindness towards individuals. But often, we come across individuals or situations that are the opposite of humanity. To describe such situations or people, several synonyms can be used in place of the term 'in-human.' Some of the synonyms that can be used are barbarous, heartless, callous, cold-blooded, insensitive, ruthless, merciless, and pitiless. These terms accentuate the lack of humanity and highlight the cruelty associated with the situation or individual concerned. The use of synonyms for 'in-human' can be vital in highlighting the severity of certain situations and the need for swift action to restore the balance of humanity.
