The Logical Atheist

Why does Yahweh count  unintentional failures to keep his commandments as sins? How is that justice?

Isn't it weird that Yahweh was willing to absolve the Israelites of at least some sins as long as they slaughtered animals and poured the blood around the altar? Why not just ask for a heartfelt apology? All-knowing Yahweh would spot insincerity.

[S]o powerful is the influence of this sin of Adam upon the human race, that they all become liable to eternal torments on this account. One would have supposed that after having brought temporal death into the world by this transgression, and after having corrupted every moral principle of the human heart, the contrivers of the scheme might have been contented, without annexing to this crime any other fatal consequences; but fanaticism and superstition delight in murder, misery, and eternal fire; and to this flaming lake I wish them a speedy passage, never more to rise to insult the dignity, or destroy the happiness of the human race. --Elihu Palmer (1764-1806), Principles of Nature; or, A Development of the Moral Causes of Happiness and Misery Among the Human Species
