You all seem to forget one thing. From the beginning, God (Jesus) knew that Jesus' death would occur. It was all part of God's perfect plan. How else could all of mankind be offered salvation. So does it matter who or what was the tool? Perhaps the killers of Christ should be feted instead of condemned. Without them God's perfect plan would not have come to fruition.
It seems very strange to me that that a religion based in the principle that all can obtain salvation condemns the very race from which their saviour came. Surely this must be an anathema to God. Fie on any Christian who condemns anyone for they have not even learned the most important of Christ's lessons: forgiveness.
