The historical events surrounding the death of Jesus are complex and subject to various interpretations. According to the Christian tradition, the Jewish religious leaders and the Roman government were both involved in Jesus' crucifixion. The Gospels in the New Testament describe Jewish leaders as seeking Jesus' arrest and execution, while the Romans, under the authority of Pontius Pilate, carried out the crucifixion. However, it is essential to recognize that the Gospel accounts were written by early Christians, and these accounts reflect their perspectives and understandings of the events. The historical circumstances and motivations behind Jesus' death are open to debate and interpretation, and it is not accurate to assign sole responsibility to either the Jews or the Romans.
Did the jews or rome kill jesus?
Pretty bad answer.
Did Pontius Pilate cave and illegitimately use the power of the state to both execute an innocent man and free a convicted murderer?
How is that a bad answer?
Because far too many people on this site treat The Jews the same way Feminists treat The Patriarchy.
That seems like a reasonable nuanced answer. Seemed like everybody listed had a hand in his lynching.
