Blood atonement was once a teaching of the Church of Latter-Day Saints (the Mormon Church). Brigham Young first preached about blood atonement in the 1850s, though Joseph Smith may have thought of it first.
Blood atonement taught that murder is so bad that the murderer could only atone for their sins by being killed. This was sometimes called "blood-for-blood" punishment because it was used to punish murder. However, sometimes it was also used for non-violent crimes, like denying or leaving the church and marrying someone of a different race.
At one time, most Mormons believed in blood atonement. Today, only some fundamentalists do.
