- The quality of being humane; kindness; benevolence
- All humans being collectively; the human race; humankind.
So by definition, humanity is acting human, pretty much. Looking over history and even current affairs, it is safe to say that humans have rarely shown benevolence and kindness. So how can we, rightfully, use the words humanity or humane in order to describe actions of love and kindness. It is so clear that humans have dark, animalistic, evil qualities, and it doesn't take much to trigger them.
For a word which derives from 'human' to have such positive connotations, it mystifies me. As we are in no way a positive race. Take a moment to watch this video, Chaplin speaks some very wise words on what we as the human race, as humanity, have become.
