Why would Romans find Jesus so unbelievable?

Romans might have found Jesus unbelievable due to his humble origins and the idea that a crucified criminal could be a divine figure or Messiah. The Roman worldview, heavily influenced by polytheism and imperial authority, would struggle to accept a single God who advocated for love, humility, and self-sacrifice over power and conquest. Additionally, Jesus' message of a spiritual kingdom contrasted sharply with the Roman emphasis on political and military might, making his teachings seem impractical or even threatening to the established order.
