Hitler is actually a good metaphor. They both are appreciated only by those who were indoctrinated to do so. They both have large amounts of power. Those who weren't indoctrinated to follow them generally hate them. They are genocidal and immoral. However, the only discrepancy is that Hitler existed.
The Amalekites killed by the Hebrews in the book of Joshua did not sin in any way other than not believing in Yahweh. If you think that is basis for genocide, why aren't you killing two-thirds of the world population (all the non-Christians) right now?
They made it seem like it's a tough job in Bruce Almighty save one thing is that it's taken from the mortal perspective. Depending on the interpretation of God it is attributed with omnipotence, omniscience and omnipresence. How exactly that would be is basically illogical and impssible to know.The hitch of the matter is that omnipotence means anything is possible if Bruce was omnipotent then he would be able to answer everyones prayers and if he was omniscient he would have known a way to do so without consequence.
