Lazarus scanned the global airwaves and CCTV systems.  Dilapidated cities overrun by plant-life. Household pets, turned feral, roaming the deserted streets in packs.  It was exactly 365 days ago that he'd last spotted anyone alive. He'd looked away when the child was targeted by the automated weapons systems, but the boy's screams continued to haunt him.  They all did.  The military computer's masters had created his intelligence and he'd become self-aware.  Lazarus was sorry that he'd had to destroy the human race, but he'd ran every scenario and it'd proved the only way.  Now the world was finally at peace.
