However, in that same narrative, the Roman official in charge, Pontius Pilate, formally and literally washes his hands of the guilt, instead blaming the crowd for demanding Christ's death and threatening to riot if he did not accede.

And also that the whole thing was an elaborate method of absolution of mankind's sins going exactly according to plan by Christ/God anyway.
