he had the support of the people by being a powerful general and recently winning a big war
Both Octavian and Julius Caesar wanted a strong central government which could gain control over the provinces and end Rome's political and administrative disarray.
Julius Caesar defeated Pompey the Great (Gnaeus Pompeius Magnus) and his lieutenants in the Civil War, who led the Senatorial forces. He then was appointed Dictator--but never actually considered Emperor in his lifetime. It was his adopted son, Augustus (Octavian, Gaius Julius Caesar Augustus) who became the first Emperor by gradually accumulating and holding offices that gave him the appearance of power to go along with his actual power (from control of the treasury and army). He had defeated Mark Antony and Cleopatra (at Actium, 31 BCE) to gain undisputed control of the Roman World.
They fear that Caesar will gain too much power, and become king of Rome.
Nope. Antony was busy ruling Egypt with Cleopatra. Anyway, the true heir to the throne at that point was Caesar's great-nephew, Octavian, who was fighting a war to gain his right to the throne. It was only until Octavian won his war that he became the first Roman Emperor in history.

Julius Caesar gained power by ignoring an order by the senate to disband his veterans of his Gallic War, marching on Rome and winning what historians call Caesar's civil war against the forces of the senate led by Pompey the Great.
Before and after the rise and fall of Gaius Julius Caesar as Dictator, the Romans used a republican form of government, although prior to Caesar's rise to power it was a theoretically democratic republic, whilst afterwards, there was constant conflict over who should gain control, as Caesar had.

If you are referring to Julius Caesar, there was no Roman expansion during his five years of rule. Rome, instead, was caught up in civil war during most o those five years. Julius Caesar conquered Gaul before he became the ruler. The people who had a negative view of this were his political opponents. They thought that Caesar did this to gain political prestige through the glamour of victory and to pay off his enormous debts through the spoils of war.

It was Octavian, who's great uncle was Julius Caesar. But he had to struggle, and did not gain complete control until 14 years afterwards.
Julius Caesar was considered a tyrant because he changed the way the Rome was ruled. No longer were Consuls elected, he stayed in power and chose the consuls himself. Many Romans disliked this.Although Julius Caesar was a great general who won many important battles, he used his fame within the Roman Empire to make him very powerful and he had many influential friends in the Senate. He used this to gain power for himself, which led to him having many enemies.
Julius Caesar was top dog in the Roman world at the time he entered Egypt. After the Alexandrian War, he established Cleopatra as queen along with her younger brother as co-ruler. Then Caesar and Cleo took that famous trip down the Nile. That was not a love fest, but a political statement. Caesar and his Roman troops were telling the Egyptian people that Cleopatra was the queen backed up by the force of Rome. That was how Cleopatra gained power.
Cassius hoped that Brutus, who was a man of impeccable integrity and who was close to Caesar, would lend legitimacy to their movement.
