In religion and ethics, inviolability or sanctity of life is a principle of implied protection regarding aspects of sentient life which are said to be holy, sacred, or otherwise of such value that they are not to be violated.
Sacred means revered due to sanctity and is generally the state of being perceived by religious individuals as associated with divinity and considered worthy of spiritual respect or devotion; or inspiring awe or reverence among believers.
Religion is a cultural system of behaviors and practices, world views, sacred texts, holy places, ethics, and societal organisation that relate humanity to what an anthropologist has called "an order of existence".
Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct.

This applies to both animals and humans because they are holy and worthy of life.

The concept of inviolability is an important tie between the ethics of religion and the ethics of law, as each seeks justification for its principles as based on both purity and natural concept, as well as in universality of application.
