You guys are trying to get inside the mind of Jesus and I don't see how you can.
Whether real or ficticious, its a unique story.
Never had God become Man and gone through the full lexperience of being fully human, much less die in that form and feel all the pain and aguish.
We have no idea how Jesus felt or how he viewed it, none.
We know that he felt pain, tremendous pain, and we know that at one point he felt abandonded, we know that he forgave those that tortured him and we know that after his bodily resurection, He kept the marks.
Beyond that...
As for knowing that His suffering was only temporary and knowing that He would be ressurected, I don't think that would have made the pain any less or the death any less "deader".
