Well, which god are you referring to?
I assume you mean the Christian, but is that the church's? or the bible's?
I'm going to have to say that IMO there is no diety, and if there was he would display characteristics of everything, more of an "ininteligence", because frankly old testament god has some seriously negative quialities, much more akin to the angel Lucifer (aka satan) than to the idea that the catholic church likes to push.
Also, as for the greatest trick thing.. That explains why most of the world sucks ass, because a truley benevolent deity would KNOW in advance that they would eat the fruit, would KNOW IN ADVANCE that lucifer was going to trick them. Nah, what makes more sense is that lucifer kicked a pacifist god out of heaven, then set up a series of reasons to punish man, when god tried to bring the people knowledge he kicked them out and so on.
