In the Tempest Tales, Mosley distinctly separates the morals of Heaven and Harlem. I don't think he does this to villify the moral values of Harlem, but rather to question the validity of Heaven's standards in the modern world.
The people who live in Harlem have to act a certain way to survive, and also rarely have a chance to escape the conditions they live in. They have no choice but to break Heaven's rules and yet they are put into Hell. Tempest questions Heaven's ideal view that people are all born with the possibility of going to Heaven.
Do you think that the individual situations of people deserve individual moral rulings, or can the same morals apply to everyone?
