Overview
Cruelty is the pleasure in inflicting suffering or the inaction towards another's suffering when a clear remedy is readily available. Sadism can also be related to this form of action or concept. Cruel ways of inflicting suffering may involve violence, but affirmative violence is not necessary for an act to be cruel.
Etymology
The term comes from Middle English, via the Old French term "crualte", which is based on Latin "crudelitas", from "crudelis".
The word has metaphorical uses, for example, "The cliffs remained cruel." (i.e., unclimbable when they desperately needed to be climbed) in The Lord of the Rings.
Usage in law
The term cruelty is often used in law and criminology with regard to the treatment of animals, children, spouses, and prisoners. When cruelty to animals is discussed, it often refers to unnecessary suffering. In criminal law, it refers to punishment, torture, victimization, draconian measures, and cruel and unusual punishment. In divorce cases, many jurisdictions permit a cause of action for cruel and inhumane treatment.
