Most people have heard of those that seek atonement and redemption for their crimes. However, there are those who forgive and absolve others of their sins. These people are often the most noble and compassionate people around, and will sometimes go to great lengths to help those that have fallen. Some actively seek to better those that are evil while others do so by accident or nonchalantly.

Unlike the Knight Templar or The Fundamentalist, these people are NOT overly zealous, although they may be naive or overly loving.
