Julius Caesar- A Reformer or a Dictator?

I believe that despite all the great things he has done for the Roman empire, Julius Caesar was a dictator, and did seek glory for himself. For example, it is a historical fact that Caesar made some reforms to the Senate, in order to have more of his supporters in it. That way, he believed he could gurantee to stay in power, and not get overthrown by the Senate. Also, if he treated all of the defeated enemies with care, he wouldn't have conquered so much of Gaul and Britain. In order to establish new colonies and create new allies, you have to fight, and that is exactly what Caesar did. When Ceaser proclaimed the dictator of Rome for his whole lifetime, he obviously contradicted some of the basic rules of a republic. In the Roman republic, a dictator was only in charge during a time of big crisis or emergency, which led many to believe that Caesar was against Rome's original form of government.
Caesar also showed his greed for power when the Senate decided that Pompey should be the one ruling over Rome. Ceaser decided not to give up his army, and not to stop ruling, even after he has been warned. He crossed the Rubicon river, and marched into Rome with 5,000 soldiers. He knew that by doing this he would start a civil war, and yet, he still didn't care about all the innocent people that could get killed, and all the homes and farms that could be ruined, leaving many people jobless again. He wanted his power, and was going to do anything to regain it.
