Isaac Asimov's Caliban

In a universe protected by the Three Laws of Robotics, human are safe.

The First Law states: A robot may not injure a human being, or, through inaction, allow a human being to come to harm.

When an experiment with a new type of robot brain goes awry, the unthinkable happens.
Caliban is created...

A robot without guilt or conscience, a robot with no knowledge of or compassion for humanity... a robot without the Three Laws.
