Moral imbecility/moral imbecile

A category influenced by the ideas of Eugenics in the early 20th century, which labelled as a type of 'feeblemindedness' those people who were believed not to be able to distinguish right from wrong. Drawn exclusively from the poorer classes, this category might include people who would be seen today as having mild learning disabilities, but could also include people such as prostitutes, mothers of illegitimate children and criminals.
