There is a good case which can be made that the typical image of Jesus, is in fact modeled on Cesare Borgia. Since it first appears in Italy during Cesare's lifetime, the two are very similar, and no doubt artists would have seen it as, both a good joke, to make the bastard of the pope the model for the bastard son of god, and a good way to gain favour with the church powers, who would probably not get the joke.
Which leaves a billion Christians worshiping a gangster. Wonder if we should tell them ?
I could see them embracing this bullshit!
