Justice or Vengeance by asteroftherainbows
Undyne had always hated humans. They'd trapped her people and left them for dead, they'd destroyed the monsters' beacon of hope in the darkness, and now one of them had mercilessly killed soldiers and civilians alike in the name of "justice". They hated all monsters for the sins of a few. But could Undyne really believe she was any different? (T for violence and probably language)
