Pity for the guilty is treason to the innocent.
- Ayn Rand
"I regard compassion as proper only toward those who are innocent victims, but not toward those who are morally guilty. If one feels compassion for the victims of a concentration camp, one cannot feel it for the torturers. If one does feel compassion for the torturers, it is an act of moral treason toward the victims..."
