In liberal political philosophy, from Michel de Montaigne to Judith Shklar, cruelty - the wilful inflicting of pain on another in order to cause anguish and fear - has been singled out as 'the most evil of all evils' and as unjustifiable: the ultimate vice. An unconditional rejection and negation of cruelty is taken to be programmatic within a liberal paradigm. In this contribution, two anthropologists triangulate cruelty as a concept with torture (Stade) and with love (Rapport). Treating the capability to practise cruelty and the liability to suffer from cruelty as universal aspects of a human condition, Stade and Rapport aim to instantiate the precise enactment of cruelty, firstly, and secondly, to propose a process of its social negation. CIA training manuals and quotidian practice within the British National Health Service are employed as illustrative materials.
