Does God Play Dice?

If God laid emphasis only on our actions – Karma – disregarding our intentions, wouldn’t that be an unfair method of evaluating our existence? If so, then it makes God unfair and partial (Partial because, He’s the One who creates the constraints within which we have to make decisions, and He’s the One who gives us our nature which influences our decision making; He controls both the environment and the act of decision-making in us). If He does not disregard our intentions, then He has to be a little subjective in evaluation, for strict parameters in His decision-making may make Him prone to mistakes…and He can’t take the “I’ll-make-an-exception-in-this-case” stance, for that, again, makes Him partial…

So how does God evaluate our life? Or rather, does He evaluate it at all? Or does He just play Dice?
