We are dust, and when we die, we return to the dust. Our anatomy and our physiology is like that of an animal. But Scripture says that we are much more than animals. We are in some way like God himself. Social roles do not change a person's spiritual value.
All humans deserve love, honour and respect.
Genesis 2 and 3 explain that the originally perfect creation became marred. Adam and Eve ate from the forbidden tree. Humanity sinned, rebelled against the Creator, chose to go its own way. Eve would bear children, which was part of the original plan, but now it would be with great pain. Adam would till the ground, which was part of the original plan, but now it would be with great toil.
