First of all, this should be posted in the politics section, if there is one...
Now, on to the questions.
1. A truly great ruler of a country should be able to inspire people around him/her to do great for his/her country. He must also consider and balance the impacts of his/her policies on his/her fellow compatriots, and, as in modern times, on other countries.
2. A powerful ruler has to be ruthless in claiming more power for himself/herself. He/She must maintain such power to prevent being usurped. With this objective, powerful rulers usually become corrupted and absorbed in seizing power for themselves.
3. Being a good leader requires benevolence and acceptance of all opinions so as to make his/her nation a better place to live in. Being a powerful ruler, however, is independent of the ruler's willingness to make people's lives better. The main objective is to seize more power, power which will eventually corrupt himself/herself. The two are completely opposite pictures of how a person rules his/her country.
4. Commodus is a powerful ruler, with the entire Roman army at his disposal. He craves more power for hiself to sustain his totalitarian rule. Unfortunately, as he suppresses the will of the people, he eventually perishes as power-hungry rulers do.
