A communist government typically states that it is made "for the people", but in reality it generally degrades too autocracy and absolutism. From a historical viewpoint, there has never been a successful (if there even is a successful way of having) communism. The basic human nature is that a person has greed. Not only do they want what they do not have, but they also want power and absolutism. Examples of 'failed' Communist countries are Venezuela, U.S.S.R, and North Korea.
On the other hand, a democratic government allows for the necessary checks and balances (though again it is not perfect). There are two forms of democratic governments. The first is Direct Democracy. Direct Democracy is allowing each person to individually voice their opinion and vote on a matter (which can be seen as something like a popular vote). This type of voting generally works well in smaller communities in which interests are largely mutual, and ideas generally agree. An example of Direct Democracy is Ancient Athens. On the other hand, is Indirect Democracy, or the act of voting for representatives who in turn represent the ideas and beliefs of his/her voter base. An example of Indirect Democracy is the United States.
Essentially, Communism is a veil that can be used by autocrats to rise to power from the benefits of lying to not only their supporters but also their opposers, while a democratic government takes into account the will of the land and people.
