Specifically the "Dispensationalists" who believe the Rapture, the Anti-Christ, and the Great Tribulation are all in the near future. In other words, 41% of all Americans.

Suppose you found your brother in bed with your wife and put a javelin through both of them, you would be justified, and they would atone for their sins. ~ Brigham Young, 1856The notion of "Blood Atonement" was a staple of the early Mormon Church. God could forgive certain sins only by killing of the sinner in such a way his blood falls upon the ground. Both Joseph Smith and Brigham Young (Danites or Avenging Angels) had gangs who would hurry men to their salvation by murdering them. Modern Mormons claim such stories are myths. The concept of Blood Atonement survives within polygamist Mormon sects.
