True enough. But it is God -- through His servants -- who made the Jews (not the Romans) DIRECTLY RESPONSIBLE for the murder of Christ. This is something which many Christians miss.
Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain: (Acts 2:23)...Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye. Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers: (Acts 7:51,52)
We should keep in mind that Pontius Pilate tried to prevent the crucifixion of Christ several times, but because he was a coward, he gave in to the Jewish mob eventually. But God already knew this in advance, and it all worked out for plan of salvation.
