After the Lord kicked Adam and Eve out of the Garden he commanded them to work. "By the sweat of your brow shall ye eat your bread." It wasn't a curse. It was a blessing for mankind. To be able to create something useful and beneficial is one of man's highest callings. Satan, knowing man's propensity for idolness and thus idolatry, commanded Cain to worship him. Satan promised Cain a life of leisure where no work was required. All Cain had to do was kill Able and take his stuff. Thus Cain, the first true Communist, was unleashed. Communism is a form of idolatry promoted by Satan. The promise is that you will not have to earn your bread by the sweat of your brow if everyone shares. The Idol is the State. Like Satan, the promise is a lie. The goal of Communism is to enrich the truly wealthy at the expense of everyone else. In the end, once people start realizing the lie, it is too late. This is why Communists kill off their most ardent supporters. The Intellectuals, politicians and University Professors. Along with the Journalists that spread their false promises.
Cain was the First Communist.
