This is encouraged because the government policies are failures. Communism is supposed to produce limitless wealth, making all of its citizens happy and rich. But with the ability to produce impaired, the success never happens. To distract the population from its failure, the government must blame it on others. And anyone guilty enough of harming everyone in society should be killed of course. Communism lives on scapegoats.
Communism is a brutal system of government. It does not just fail to protect individual rights, it establishes a system of violence force. The results have been exactly what one would predict: starvation, poverty, and the slaughter of millions.
