In fact, not all Roman convicts sentenced to death were crucified.
Crucifixion was reserved for the lowest of the low, and most of all for those who openly opposed Roman power.
So it is really too simple to speak of “the Jewish perspective” on the necessity of Jesus’ death.
Furthermore, historical explanation doesn’t exhaust the realm of discourse when it comes to the reason for Jesus’ death.
In my opinion, as you’ll see, the pendulum that had once swung way too far in the direction of “the Jews” has now swung too far back in the opposite “Romans only” direction. I should add at this point that I am aware of the shameful history of anti-Semitism and the danger of anti-Semitism that is very much alive today.
