Jesus acted with ferocious and bold integrity when he threw the money changers out of the temple. Needless to say, he hiccuped their cash flows on what otherwise would have been a big grossing day. Their business model threatened, the priests who managed the money changers insisted that the Romans crucify Jesus. The Romans tried to pawn the problem off on the local king, Herod, who ducked and sent Jesus back to the Romans. The Romans, still looking for a way out, tried a flogging. That did not work. The priests meanwhile had succeeded in persuading the crowd to support them and scapegoat Jesus. Thirsting for a crucifixion, the crowd voted to set the criminal Barabbas free instead of Jesus.
Jesus died because the crowd voted for the criminal enterprise. The crowd voted for the priests and their rich endowments and their alliance with the money changers.
It's 2000 Years Later and We're Still Voting for the Criminals
