Answer For starters, very few Unitarian Universalists believe in Hell. Our Universalist members traditionally believed in Universal Salvation. Here is some information from www.uua.org:
At a Unitarian Universalist worship service or meeting, you are likely to find members whose positions on faith may be derived from a variety of religious beliefs: Jewish, Christian, Buddhist, naturist, atheist, or agnostic. Members might tell you that they are religious humanists, liberal Christians, or world religionists.
All these people, and others who label their beliefs still differently, are faithful Unitarian Universalists committed to the practice of free religion. We worship, sing, play, study, teach, and work for social justice together as congregations-all the while remaining strong in our individual convictions.
