The last I checked sacrifices were evil, and not something that a NG deity would condone. What do you plan to do when someone in the party makes their Knowledge (Religion) check and realizes that good deities don't condone sacrifices, thus you are not a cleric of a good deity?
Thats where the high bluff comes in, ie: when someone says "But that deity cant be demanding a sacrifi.." "Followers! seize this non believer, he tried to weaken our faith!" ::Bluff and Diplomacy Check::
