Why did Roman officials and many Jewish leaders regard Jesus as a troublemaker?

The only Roman official with whom Jesus ever interacted was Pontius Pilate. All the other Romans with whom He interacted were soldiers and functionaries [tax collectors]. None of the soldiers who interacted with Him ever displayed any fear of Jesus. Many believed in Him, trusted Him, and asked Him to intervene for them. That leaves Pilate. Pilate wasn't afraid of Jesus either. If he had been, he wouldn't have sentenced Him to death. No, the people whom Pilate feared were the people in the crowd in the judgment court where Jesus was tried. It was their threat to begin an insurrection that he feared. That's why he caved in to their pressure. So - Who's next on the officials list?
