I am not sure that he ever claimed to be divine. That is likely something made up after his death.
Just like Jews calling for his murder could have been made up. We simply have no verification of the degree of accuracy of just about anything in the Christian scriptures, as they have been changed many times over the centuries. Note that the Romans certainly had motivation to murder him if he was viewed as a threat to order in Judea.
In the Babylonian Talmud the writers are almost gleeful that the Sanhedrin condemned Christ.The writers don’t even mention the Romans.
That's your problem: you're not sure.
