We will have a constitution that protects and preserves the communist system in law, but we cannot ignore the interests of the people except when such interests conflict with the communist constitution. Only a democracy can be expected to carry out the interests of the people.

So in effect, the people do not have a full say over the government that they elect. Theoretically, if the dictatorship of the proletariat comes to reject communism, would your system move to deny them the right to choose their own destiny, even if it means exploiting one another?

On people using human nature, namely greed, as an objection to communism or even an argument, read on.

You should know that, as with nature, the free marked, or the society ruled by the marked, does nothing without a purpose. For example; in nature, atoms goes together and creates a molecule, because of magnetic energy. In the society we live in, everything is done according to capital, money. If anything is profittable, even in the short term, it is done. It is like an energy that drives us all, or every corporation that is.

Think about what is proffitable. What makes corporations grow, and would they do what it takes to grow? In most cases, yes, they would. Imagine you were a big shot businessman of some sort, selling a worldvide product. What would you earn the most from, just imagine, in the whole world? Greed.

Greed is merely a product of the anarchic economical situation we see today. As long as the marked, or society, does not radically change, greed will always exist.
