The person most famous for popularizing vasectomy was Harry C. Sharp of the Indiana Reformatory. Certain that the criminal class had inherited deficient faculties of self-restraint, Sharp believed that regardless of the virtue in their hearts, some criminals simply could not contain their passions. Their propensity to crime and other forms of immorality was inborn since, as Scripture taught, "nature punishes those who violate her laws," and the "punishment is visited unto the third and fourth generation."
