ressentiment

Ressentiment is a sense of hostility directed at that which one identifies as the cause of one's frustration, that is, an assignment of blame for one's frustration. The sense of weakness or inferiority and perhaps jealousy in the face of the "cause" generates a rejecting/justifying value system, or morality, which attacks or denies the perceived source of one's frustration. The ego creates an enemy in order to insulate itself from culpability.

Romantic melancholy, that dark longing to deify something, simply cannot exist without the rotten core of ressentiment.(Thomas Pfau, Romantic Moods)
