What concern did Romans have about Julius Caesar?

They were afraid that he will introduce some type of dictatorship in the country and take the full authority in his hands. Rome was a Republic and people believed that other forms of government are unacceptable.

Explanation:

Julius Caesar was a great warrior, general, even a writer. But, when he emerged as a leading figure in Rome, some people, especially in the Senate were afraid that he will destroy the order in the country. Romans had in their memory a period of Kings that lasted for almost 250 years, and have vowed not to allow anyone to reign as the kings did. That is why some of them plotted to kill Caesar.

social contract theory basically says that all individuals are born equal, and provided a god given right to consent to be governed. american government is based of this

thomas hobbes and john locke said that we are selfish, individualistic, and constantly at war with each other, therefore we need to be controlled. 

government is defined as the legitimate use of force to control human behavior within territorial boundaries, here comes in hobbes and locke.

hobbes takes the part about controlling human behavior. while locke takes the part of legitimate use of force, since force is not legitimate unless there is consent of the people. 

there are basically 3 goals of the government: 1) maintain order by protecting life and property. 2) providing public goods, those which are typically not provided by the public sector, such as roads and education. 3) promote equality be it political, opportunist or outcome equality.
