eighteen years, whether arising from inherent
causes or induced by disease or injury. Moral
defectives are usually endowed with an ave-
rage degree of intellect, but cannot control
their immoral conduct, instincts and emotions
and cannot be made to understand that they
are doing a wrong act. They are dangerous
to the community, inasmuch as they are lack-
ing in moral sense and have no regard for the
rights or feelings of others. Punishment has
