As we have discussed in the past, Mormonism embraces at least a quasi-universalism in its teaching that hardly any of the inhabitants of the earth face an eternal hell after this life. And if it turns out that there is progression between kingdoms (an idea that has had both detractors and supporters among Church leaders over the years) then an even more robust form of universalism exists.
But as we have also discussed, it is not clear that it is useful to Mormonism (or to God for that matter) for all Mormons to embrace a more robust universalism even if it turns out to accurately represent reality. That is because universalism tends to kill motivation to repent and to work hard in the church. Why? Well to use the old “carrot and stick” motivation analogy (where the stick = negative consequences for actions and the carrot = positive consequences) universalism completely removes the “stick” when it comes to religious motivations.
