What role did terror play in the formation of a totalitarian society?

A totalitarian regime implies complete control of the state over all spheres of society. In the event of terror, persecution of all dissidents is carried out (they pose a threat to such a regime), intimidation of people, which helps to achieve obedience to all established laws and orders. People begin to be afraid, obediently do what the government tells them. This is how a totalitarian regime is established, which is gradually only getting stronger.
