Atrocity is recognized as such by victim and perpetrator alike, by all who learn about it at whatever remove. Atrocity has no excuses, no mitigating argument. Atrocity never balances or rectifies the past. Atrocity merely arms the future for more atrocity. It is self-perpetuating upon itself -- a barbarous form of incest. Whoever commits atrocity also commits those future atrocities thus bred.
Humankind periodically goes through a speedup of its affairs, thereby experiencing the race between the renewable vitality of the living and the beckoning vitiation of decadence. In this periodic race, any pause becomes luxury. Only then can one reflect that all is permitted; all is possible.
