The Romans didn’t care about him one way or the other, it was the temple hierarchy that hated and feared him. They begged the romans to do their dirty work for them.
And to the morons that claim the Jews killed Jesus, yes. And they were the ones that mourned him and the ones that carried on with his teachings and at one time it was the Jews (Paul and John if I remember) that had an argument about having to become Jewish first before you could call yourself a Christian.
