Naturally, family is the reflection of humanity. Or better yet, family is the origin of humanity.
In the family, mother gives birth to a child who will then become a full grown adult, Mother and father will both raise and care for, protect, feed and cloth, educate, and love the child; and these are natural reflection of humanity.
Family spawns humanity.
But, when a child is abandoned when born or deserted by the parents, there is no humanity because it is NOT a family.
Furthermore, when there’s abusiveness and/or adversary among family members, there is no humanity because it is a broken family.
