Lacking compassion or kindness; cruel and brutal, or not having human qualities.
From Latin 'inhumanus' (not human, savage), combining the prefix 'in-' (not) with 'humanus' (human), where 'humanus' relates to 'homo' (man/mankind).
Calling something 'inhuman' is actually a category error—it assumes humans are inherently compassionate, when really inhumanity comes from humans choosing cruelty, making it deeply human after all.
