What is the historical significance and current understanding of the Mormon blood oath within the context of the Church of Jesus Christ of Latter-day Saints?

The historical significance of the Mormon blood oath, also known as the Oath of Vengeance, dates back to the early days of the Church of Jesus Christ of Latter-day Saints when members vowed to avenge the death of their prophet, Joseph Smith. This oath was later disavowed by the church and is no longer practiced. In current understanding, the blood oath is seen as a controversial aspect of Mormon history that reflects the intense persecution and challenges faced by early members of the church.
