ethics discussion

“Discuss Benthams’s claim that punishment is an evil (Boss, 1, p. 249). Can punishment, including capital punishment, be justified on utilitarian grounds? Or does punishment of criminals actually decrease the overall happiness of society, as Bentham maintains? What policy would a utilitarian most likely propose for dealing with potentially dangerous criminals?
