Are you kidding? We, as humans, have poisoned our nest and are on the brink of vaporizing it, if not merely decimating the life-forms of the planet, and you call God's game of 'Hide and Seek' callously dangerous'? Roughly speaking, human beings are probably living at about 5% of their actual potential, mostly nurturing greed, nationalism, racism, warfare, etc. The key to realizing our true potential lies in the nurturing of world peace through Higher Consciousness. World peace is not merely the interlude between wars, but involves a complete transformation of the human mind resulting in a spiritually-awakened state of being. Once this awakening occurs, our new vision clearly reveals the true nature of reality that lies behind the illusion that is the world. But it is because we are deluded that we mistake the world as real, and act destructively, in the sense that we imagine it as an object of desire, and in pursuit of this illusion, we create the negative conditions we experience, which, in turn, continue to drive the cycle of cause and effect in the name of some concept of The Good, such as 'The Inquisition', or 'Manifest Destiny', and even 'World Peace'.
It seems to me that you are still responding negatively to the concept of the ruthless, sadistic God of the Old Testament, that is just an extreme egoic projection. This God is not real. When it became too rigid, a more compassionate balancing counterpart to the all-male God had to be concocted in the myths of Jesus and Mary. I think the key for you is to try to understand these anthropomorphic images of divine beings as principles within man's psyche, which, in some cases, are out of balance and manifest themselves externally as, in this case, a rigid, moral authoritarian. It is exactly for this reason that the mystical view is necessary, as it provides the required feminine essence to soften such a view.
And so, as humans, we first project the image of a ruthless God, and then proceed to emulate his approach in dealing with the world, rendering the 'callously dangerous game' none other than our own.
