Is the Gospel of Jesus and fishermen disciples a peaceful way (peace propaganda by Rome) of describing a battle-violent Jesus and fishermen disciples?

Jerusalem was given a crushing defeat, a devastating defeat. They not only lost the war but lost their religion, Temple Judaism. There were no heroes until the legend of Jesus and fishermen disciples was invented. No, the killed, bloated, stinking bodies from the losses of Jesus and his fishermen rebels at the battle upon the Sea of Galilee would be countered with legendary miracle of Jesus walking on the waters of the Sea of Galilee.

This legend was written to lift the spirits and to give the defeated some heroes in a war they loss terribly.

To do that Jesus and the fishermen disciples had to be moved back in time from a time of violent messianism to a time of relative peace between Jews and Romans, some decades earlier.

Give them a legend that runs aground. Make Jesus give them a ritual of defeat (cannibalism in Judaism is indicative of defeat); make Jesus give them a ritual that separates People from God (in Judaism, drinking blood causes their God to turn away his face–that they seek.) They seek but never will find with this legend.
