I was actually thinking about responsibility. For example if I jump in front of a train and die, I am responsible for my own death, not the train driver; if I live, I'm guilty of attempted suicide while the train driver is not guilty of attempted homicide. But even if we call Jesus responsible for going to Gethsame, it still sounds like nonsense to say he's responsible for his own death, since surely Pilate/Judas etc had the choice to not bring about Jesus's death.

But if they had the choice to not bring about Jesus's death, then prophecies would be invalidated and Jesus would be wrong, which sounds just as nonsensical

What's the alternative as well - to call all of them responsible since they're all part of a greater plot to get Jesus killed to strike a death blow in a spiritual war against the devil?

@Allure The standard Christian explanation is that God anticipates (foreknowledge) but gives meaningful free will to the agents that were responsible for Jesus's execution: Pilate, Judas, and the High priest. All 3 agents acted true to their characters, which were formed through many years of living prior to the Gethsemane night. It's like God the Father knew them intimately just like a father knows what his teenage boy would do when he is not at home.

If we read the Gospel of John from beginning to end and take into account the cultural and historical background (by reading history books, etc.) we can see how the actions of those 3 characters that night flew naturally from their previous encounter with Jesus. So all 3 were responsible. Jesus then took advantage of the situation and added his self-giving love into the event to complete His mission.
