In contrast to the value-laden definition, proponents of the value-neutral definition of capabilities and functionings hold that doings and beings can be both positively and negatively valued as well as normatively neutral. A capability, according to this definition, is simply the freedom that people have to do or be certain things. Examples of capabilities that are usually evaluated positively are being well-nourished, sheltered, and educated, while examples of capabilities that are usually negatively valued are the ability to kill (Stewart and Deneulin 2002, 67), the ability to rape, being vulnerable to natural hazards, and being able to pollute (Holland 2008, 418; Nussbaum 2006, 166). Because both positively and negatively valued capabilities determine how well-off we are, it is necessary that capabilities are defined in a way that includes both.
