In Christian ideology, his suffering and death was the suffering and death we were all supposed to have. He took that suffering and death so we don't have to, the "perfect lamb".

Looking at just that suffering on that one day is missing the context for everything else after, at least according to Christian ideology.

Also, an important part of the completion of previous prophecies for those looking at the older books. Jesus wouldn't have been the savior if those things didn't happen to him, according to the texts.

Oh thanks, but since I was also raised catholic, I am aware of the theory.

Still, the main visible symbol, is rather one of death and suffering to me.

Jesus does not look happy on those crosses, where he also has a face.
