 Other philosophers have suggested that evildoers desire to cause harm, or to do wrong, for more specific reasons such as pleasure (Steiner 2002), the desire to do what is wrong (Perrett 2002), the desire to annihilate all being (Eagleton 2010), or the destruction of others for its own sake (Cole 2006). When evil is restricted to actions that follow from these sorts of motivations, theorists sometimes say that their subject is pure, radical, diabolical, or monstrous evil. This suggests that their discussion is restricted to a type, or form, of evil and not to evil per se.
