Context

“My contention is that all the highest values of humanity have been emptied of this will -- that the values of decadence, of nihilism, now prevail under the holiest names. 7 Christianity is called the religion of pity. Pity stands in opposition to all the tonic passions that augment the energy of feeling of aliveness: it is a depressant. A man loses power when he pities. Through pity that drain upon strength which suffering works is multiplied a thousandfold. Suffering is made contagious by pity; under certain circumstances, it may lead to a total sacrifice of life and living energy -- a loss out of all proportion with the magnitude of the cause (--the case of the death of the Nazerene)” source
