La personnalite perverse.

From the clinical point of view, the perverse personality is characterised by constant manipulation of others, transgression of laws and disrespect of limits. Perversity does not refer to the presence of a sexual perversion, whether primary or associated, but to the fact that a same basic principle underlies the organization of the perverse personality and of the perverse sexuality. Both forms could thus be understood as two different manifestations of intolerance to disappointment. This general hypothesis avoid some questionable speculations and ad-hoc hypotheses.
