//Does he 'hold an important mirror to our own human condition'? //
For some reason, I am unable to process this question properly because the customary context for its use is when it is about an artist, "holding a mirror to reality", or "reflecting on the human condition". You shouldn't have to put it into different words but it would help me, greatly.
//Would Jesus have forgiven him? //
I thought he did forgive him? More than that, he all but ordered him to "do what must be done" (or equivalent). Chosen for the task, not merely the person who was standing close by when the task came to mind.
The ultimate in "taking one for the team" dirty jobs.
It is peculiar though. God could have terminated his earthly presence at any time, by any means and achieved the whole sin-redemption end-goal but, as atalanta said, that would mean no cross and, if it was a particularly destructive form of death, resurrection might have been an awkward business.
So why drag Judas, the disapproving senior clerics, Pilate and sundry Romans into this whole theatrical denoument? Man must betray Jesus and carry out his execution? Why?
Okay, I realise that the Resurrection doesn't convince unless we have a definitive death, in front of many witnesses (under dramatic skies etc.) and the suffering is important so it has to be crucifixion, not decapitation.
One Gaulish rebel leader was, famously, taken to Rome, imprisoned for some time, then paraded through the streets before being ritually garotted. Strange how Jesus (rebel leader) wasn't subject to this traditional punishment.
