Even the whole "getting killed by the Romans" part doesn't make any sense. Why would the Romans care about killing a man who claimed to be the Jewish messiah? They certainly wouldn't release a murderer in favor of executing a blasphemer against a religion they didn't follow.
The "Jesus" spoken of may have been a small political figure perhaps . I have no clue nor does anyone else truly as to who or what Jesus was. But all insignificant events can be pushed into a state of glory and splendor despite their insignificance.
Rumors spread and they spread fast. The very fact that any person claiming to be the "King of the Jews" is an assault to any sensible empire as declaring authority over a territory which is subjugated is not exactly an ideal thing to do.
Jesus's actions could have been perceived as an act of aggression against the Roman empire perhaps?
