Ressentiment

Ressentiment is one of the forms of resentment or hostility, of particular interest to some 19th century philosophers, like Friedrich Nietzsche. According to their use, ressentiment is a sense of hostility directed toward a object that one identifies as the cause of one's frustration.

The sense of weakness or inferiority complex in the face of the "cause" generates a rejecting/justifying value system. This value system may then be used as a means to justify one own's weakness by identifying the source of envy as objectively inferior. The ego, hence, creates an enemy to insulate themselves from culpability.
