نسل کشی جنایتی علیه بشریت است که شامل یک اقدام عمدی و برنامه ریزی شده با هدف نابودی یا کاهش قابل توجه، به طور کلی یا جزئی، یک گروه خاص ملی، قومی، نژادی یا مذهبی است.

نسل کشی یکی از جدی ترین جنایات جنگی و جنایت علیه بشریت محسوب می شود. معمولاً در زمان جنگ یا درگیری مسلحانه انجام می شود، اما می تواند در زمان صلح نیز انجام شود.

نمونه هایی از این جنایات عبارتند از هولوکاست، نسل کشی ارامنه، کشتار در رواندا و پاکسازی قومی در یوگسلاوی سابق. همه آنها با قتل جمعی، شکنجه، تجاوز جنسی، و همچنین جابجایی اجباری و سایر اقدامات با هدف نابودی یک گروه انسانی مشخص می شوند.

نسل کشی یکی از بزرگ ترین موارد نقض حقوق بشر و اصل احترام به جان انسان ها محسوب می شود.

Howard Stanton Levey (April 11, 1930 – October 29, 1997) was a founder and high priest of the Church of Satan. Biography: LaVey spent most of his life in San Francisco, California. In his youth, he was, m.in , a circus animal keeper, organist, and then a police photographer. At the age of 18, he became a magician's assistant; He studied the occult and learned hypnosis. In 1951, he married Carole Lansing. At the age of 24, he quit his job and returned to playing the organ. He continued to study his life's passion – black art. Once a week, he gave lectures on the mysteries of haunting, ESP (extrasensory perception), dreams, vampires, werewolves, prophecy, ceremonial magic, etc. They attracted many listeners. Finally, the Magic Wheel emerged from the group. The main purpose of the circle was to meet in order to perform magical rituals discovered or developed by LaVey. He has compiled an entire library of works describing black masses and other ceremonies by groups such as the Hellfire Club and the Hermetic Order of the Golden Dawn in eighteenth- and nineteenth-century England. Some of these secret orders or organizations intended to address the devil as an anthropomorphic deity representing the opposite of God. Rather, according to LaVey, Satan is the dark, hidden force of nature responsible for the course of earthly affairs, a force that neither science nor religion can explain, the spirit of progress, the inspirer of all the great movements that have contributed to the development of civilization and the progress of humanity, the spirit of rebellion leading to freedom, and the embodiment of all heresies that lead to liberation. In 1960, LaVey divorced Carole and became involved with Diane Hegarty. After separating from her, he married Blanche Barton. At the end of 1966, he established the Church of Satan. His main work, presenting the foundations of Satanism, is the Satanic Bible, written partly in English, partly in the Enochian language. In his private life, he was interested in music, paintings, vintage cars, firearms and animals (especially big cats). He spent the rest of his life with his wife (Blanche Barton), son Xerxes, and daughters Karla and Zeen. He died of pneumonia.
