I don't quite buy the idea that helping one person over all others means he is being cruel to everyone else. If he takes something away from all the others to give to the favoured one, then, yes, I agree.
I like the idea of deism.
As for God's quid pro quo, I agree, what could an omnipotent, omniscient, omnipresent deity possibly want from us? Yet the accounts we have seem to speak of his anger when disobeyed and of the harshness of his retribution; of his tantrums where he meets decadence, such that he destroys cities, and, worse, how he floods the whole world, killing virtually every single person alive at the time. And, according to those accounts, all he really wanted was to be loved.
And this reveals him to be less than omnipotent, omniscient and omnipresent - or at least, it does to me.
