When most people think of the concept of the "evil dictator," they cast their thoughts towards the 20th century. When you consider the era, there were a lot of horrible dictators in power responsible for the imprisonment, torture, and deaths of millions of people.
Generally, folks like to believe we have moved beyond the totalitarian style of dictatorship common in the previous century, but sadly, that's simply not the case. There are people in power today who got their start decades ago while others are new to the game. If you live in a country led by a sane leader who doesn't allow their ego to direct them towards horrible decisions, count yourself lucky; there are millions of people all over the world who cannot do the same.
Modern dictators are much like their 20th century counterparts in that they limit exposure to outside media, employ a state-sponsored news and media empire upon their people (i.e., propaganda), and impose harsh penalties on their citizens for a wide variety of so-called crimes against the State.
Unfortunately, the days of the evil dictator are not behind us and the world remains afflicted with dangerous and horrible people - with these ten being the worst of them all.
