Because communism is despotism and tyranny and tyrants always elminatye the competition. He was acting as a communist SHOULD act.
Communism means no such thing as yous say. Nothing in communism forbids profit motive it only forbids profits for private individuals. Communism is NOT tribal or akin to families.
The problem is that communism is an evil and immoral ideology which demands people exactly like Stalin Moa kim and castro
If communism were despotism and tyranny, then why would all human societies, like families, tribes, religious communities, clubs, and all social organizations, be communist?
Eliminating the competition is EXACTLY the definition of capitalism.
Obviously you are totally confused and have everything totally backwards.
The profit motive that you get from despotism and tyranny is CAPITALISM, not communism.
Communism by definition has to be fair and equitable.
All families HAVE to be communist because you can't have a capitalist profit motive when running a household.
All hunter/gatherer tribes HAVE to be communist because the success of hunting and gathering is unpredictable, so requires voluntary sharing.
That IS the definition of communism.
You have it totally backwards, and Stalin not only was a pure capitalist, but is who created Mao, Kim Jun Un, and Fidel Castro.
