The other thing I wonder about is why the crucifiction was necessary? Is God not powerfull enough to just forgive sin without having his son killed ?
I have never understood the fascination God had with blood.
From at least the time of Cain and Abel, a central theme of the bible is God's desire that we sacrifice what is most important to us to Him. Rather than keeping everything for ourselves, through our sacrificing comes that acknowledgement that everything that we have been blessed with comes from the God. If not for the grace of God, we have nothing.
God's willingness to sacrifice Himself in the body of Christ signifies that He desires that the relationship between Himself and ourselves be one of reciprocity. He does not ask of us to give Him any more that he freely and willingly desirous to give Himself. Through His death on the cross, his willingness to even give His Life for us is amply demonstrated.
Love requires reciprocity. We sacrifice for Him not because He demands it, but because we love Him and want to. His pleasure becomes our pleasure, and vice-versa.
In so many ways, Love is Sacrifice. To love a child or a spouse, we are required to give up so much of our time and independance, and to put their needs before our own wants. Yet we do so because we want to. The rewards of love are so much greater than what is sacrificed. When we truly love somebody we are willing to even give up our lives so that they may live. Through the cross, God shows us that He is so also so willing.
I think it would be incorrect to believe that God has a facination with blood or takes any pleasure in our suffering. Scripture tends to explain suffering as the result of mankind forsaking God, and pursuing our own needs with no regard for what He might want. Because mankind turns away from God, and forgets that Love is the true basis of our relationships with another, the cross and other instruments of torture become the expression of a heart that is unwilling to submit to the sacrifices that Love requires of it.
Edit: It is not so much a question of power or powerlessness. To force our love on another or impose our will upon them just because we have the power to do so would be akin to rape. Love requires more.
