It all depends on the man ruling. History shows us that there have been a few good dictators, but many aren’t. “Power corrupts and absolute power corrupts absolutely”. Humans have an insatiable thirst for power. We enjoy having authority over something or someone else. Be it an animal, a spouse, a neighbor, an employee, another kid on the playground… We’ve all seen many examples in our lives and we’ve probably even had the desire ourselves.
When humans first established governments, it was usually the strongest or the wisest who first ruled. Then their kin would succeed them (creating dynasties). The more powerful rulers conquered the weaker ones, thus establishing nations. Of course, the bigger the nation, the more power it wielded. And the more power it had the more tempting it was for the ruler to abuse that power. Some ancient rulers were so deluded by power that they demanded to be worshiped as gods. If a god says bow before him and a person refuses, or if they publically disagree with him, there’s no “freedom of speech” or “I have my rights”. No, that person is usually jailed or executed… right there on the spot. Yikes!
