Was Julius Caesar a tyrant or a good leader?

Julius Caesar was loved by the soldiers and the common people, but despised by the upper class for how he came to power. 

Julius Caesar was a brilliant military tactician and leader. He got along with almost everyone because he was a Patrician but did not come from a wealthy background. He had an ear for languages, which made it easier for him to interact with leaders from other countries—even those Rome was fighting or conquering. 

Caesar’s leadership style was to lead from the front. A good example of how much he was admired and respected The fact that he was so admired and respected is that he was able to get his army to march on Rome, which was illegal. It horrified the senators in power, especially Pompey. It showed them Caesar had more power than them, because he was backed by an army willing to do anything for him. Caesar’s army was loyal to Caesar. He made them a lot of money. In Ancient Rome, soldiers were paid partially in spoils. 

Caesar was an avid reader and a prolific writer. He had knowledge in a wide variety of fields, from geography to engineering, and was a skilled speaker. He could encourage and motivate his soldiers and (usually) convince the senate, too. A group of senators felt Caesar was gaining too much power, though. They decided to stop him by stabbing him 23 times on the senate floor.

A tyrant is someone who is exacting and only cares about himself. He exerts his will on others. Brutus called Caesar a tyrant, but the people of Rome and Caesar's soldiers do not seem to have agreed with him. For some time, the senate was mixed on the issue and unsure who should have power. Eventually, they sided with Antony and Octavius (Caesar's heir), who formed a second triumvirate with another of Caesar's lieutenants, Lepidus.

What Brutus really objected to was that Caesar came to power by driving Pompey out. Ancient Rome was not the stable, quaint republic Brutus imagined, though. It had faced violent upheaval and civil war for years through Gaius Marius, Sulla, and the first triumvirate (where Caesar shared power with Crassus and Pompey). The assassins were a little idealistic in calling Caesar the villain.
