I do not get my theology from fiction. Please stop thinking that God is looking for vengeance. For reasons that we do not know or understand yet, due to the nature of God and the nature of our souls, certain actions weaken and ultimately destroy our souls. These are called sins. That is why God hates sin, they keep us from being able to withstand His Presence for all eternity. Due to the Fall, Heaven was closed to humanity and a sacrifice was needed to redeem us from this deathly situation that we were in. No mere human could accomplish the sacrifice that was necessary, so God chose to sacrifice Himself for us in through His Word made Flesh. Yes, God does not want us to be apart from Him and Jesus did feel that full separation from the Father on the cross, but it was a sacrifice- a sacrifice of the Greatest Love, NOT for vengeance , but for Love.
