Just curious as to how civilized people could do this?

How can anyone not only applaud but worship a being who by their own belief committed m murder on a planetary scale. How can anyone worship a psychotic who "hardens the pharohs heart" and then m murders the first born egyptian children cause the pharoh wouldn't listen (consider the pharoh had no choice if you believe the tripe). How can any rational reasonable civilized human being not only support but worship such a psychotic monster?
