Ask a Theist, cont'd
Why would Yahweh demand that "his chosen people" celebrate his repeated brutal collective punishment of the Egyptians (the 10 plagues), including his killing of all firstborns, even infants, especially when he himself admits that eight times he "hardened Pharaoh's heart" after Pharaoh promised to let the Israelites go, and Yahweh did this just so he could display his awesome power? (Hint: he's a narcissistic, megalomaniacal psychopath?)
