Communist morals follow a simple formula. Anything which Promotes the communist cause is good; anything which hinders it is bad. Upon examination, that philosophy turns out to be a code of opportunism and expediency, or a code of no morals at all. Anyone who does not conform to the dictates of the Party as to what is good for Communism and what is not, is subjected to the most severe penalties under Articles 131 and 133 of the Soviet Constitution. Thus, the perfect example of "class" morality, which the Marxists attribute to the Judaic-Christian code, is to be found right in the Communist plan of action itself.
