Explanation: In Christian mythology, the Romans crucified the chief religious figure of Jesus Christ.

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.

... this would unfortunately contribute to antisemitism in later Christianity, with the Jews being blamed for Christ's death by some Christian groups, despite Christ being... you know. A Jew himself.

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.

I could be wrong but weren't the Sadducees(who were the high priests) responsible for his execution?

The priesthood were part of the Iudeans calling for his death, but Romans were generally touchy about under whose authority any criminals were put to death. Thus, the appeal was to the Roman magistrate, who unambiguously had the authority to put any provincial to death for basically any reason that wouldn't trouble the Emperor himself back in Rome.

IIRC the Pharisees are mainly mentioned in that part.

Besides what pug says, it was Roman soldiers who are recorded actually physically putting him up (giving him the crown of thorns, stabbing him in the side and so on).
