Tlazolteolt is the goddess of purification, steam bath, midwives, filth, and a patroness of adulterers. In Nahuatl, the word tlazōlli can refer to vice and diseases. That's why Tlazolteotl was a goddess of filth (sin), vice, and sexual misdeeds. But she was a purification goddess too, who forgave sins and cured diseases caused by misdeeds, particularly sexual misdeeds.
