Not really a religious person but, "Greater love hath no man than this, that a man lay down his life for his friends." Bible, New Testament, John, 15:13. That sets humanity apart from other animals for me. This is maybe not so much about a belief in God, but about the ability of humanity to make sacirifices that other animals do not.
The ability, willingness, and creativity to rise above whatever comes along also defines the best about humanity for me. While other critters wallow in the mud, humanity has been able to make adobe, bricks, and mortar, then even build a house. The house can sometimes even become a home and offer warmth and shelter to humans and animals alike.
But no, not all humans are humane, not by a long shot.
