The above considerations emphasise the need for effective protection of the community: in cases of extreme violence, the chances of remission are slim and, consequently, in the event of release, the risk of re-offending is high (Hare et al., 1992). If the processes of authoritarianism are not yet structured, the psychopathic aggressor's mental apparatus can lend itself to re-organisation (Moffit, 1993). This implies, however, as Peter Suedfeld and Bruce Landon remarked, that “therapy works best with those who need it least.” (Suedfeld and Landon, 1978, p. 369) Detention presents a similar dilemma: it works best with the less dangerous individuals, who are still able to feel remorse for the suffering inflicted and who are willing to adapt to the rules of social life.
