The idea that love is not enough is a particularly painful one. In the face of its truth, humanity has for centuries tried to discover in itself evidence that love is the greatest force on earth.
Jesus is an especially sad example of this unequal struggle. The innocent heart of Jesus could never have enough human love. He demanded it, as Nietzsche observed, with hardness, with madness, and had to invent hell as punishment for those who withheld their love from him. In the end, he created a god who was "wholly love" in order to excuse the hopelessness and failure of the human heart.
Jesus, who wanted love to such an extent, was clearly a madman, and had no choice when confronted with the failure of love but to seek his own death. In his understanding that love was not enough, in his acceptance of the necessity if the sacrifice of his own life to enable the future of those around him, Jesus is history's first, but not last example of a suicide bomber
