The First Step to Triumph.
God is both absolute love and absolute justice. The rebels say that absolute love and absolute justice cannot co-exist in one being; love only forgives and justice only punishes. He had to be one or the other. The cross answered that dilemma. At the cross absolute love and absolute justice meet and become one. That is part of the meaning of the cross.
Satan is running out of options as the world that he is (temporarily) master of is collapsing around him. God's vindication is approaching. The cross appeared to be a disastrous and tragic defeat but was in fact the first step to absolute triumph. It appeared that all was lost but it was only the start of God's answer to Lucifer/Satan.
Here are two videos of Christian musicians describing the horror and hidden triumph of that day. (Both of which were recorded in the 1980s)

And also here is Too Small a Price from Don Francisco.
One of the saddest things is reading blogs by "modern Christians" who criticized Mel Gibson's The Passion of the Christ as a sadistic blood bath. (Mel Gibson is by no means a perfect man, but that movie was the achievement of a lifetime.) That so-called bloodbath is at the heart of our faith. It was the end result of all sin and it showed our sin in all its true horror. When he was being challenged for Antisemitism, Mr Gibson was asked "Who crucified Jesus?" and he truthfully answered "I did." That is the only correct answer and it is the answer for all of us as well. Every single man and woman who ever lived (except Jesus Himself of course) crucified Jesus; He is the only true victim of human history and He is the only true victor, as the world saw a bit later.
