Abstract
In this chapter, political philosopher Alex Leveringhaus asks whether Lethal Autonomous Weapons (AWS) are morally repugnant and whether this entails that they should be prohibited by international law. To this end, Leveringhaus critically surveys three prominent ethical arguments against AWS: firstly, AWS create ‘responsibility gaps’; secondly, that their use is incompatible with human dignity; and ,thirdly, that AWS replace human agency with artificial agency. He argues that some of these arguments fail to show that AWS are morally different from more established weapons. However, the author concludes that AWS are currently problematic due to their lack of predictability.
