A person consciously with painful psychopathic troubles and having no hope of recovering to a normal psychologically healthy life may get feeling helpless and may resort to commit suicide.
Of course there are persons that while having psychopathic addiction they will be struggling for a survival, perhaps much at the expense of others. Persons that more or less consciously will use their psychopathic inclination may try and contrive strategies, perhaps a vicious malicious behaviour for their own and better survival.
While psychopathy generally is defined a mental illness that makes people behave in an abnormal dangerous perhaps violent way, there are ever some slight wondrous or even weird differences between persons of even the same culture in this world, so a psychopath may behave in a particular noxious and also self-noxious way, or even in a ... "saintly" way!
Being much conscious and so suffering from the mental disorder, the psychopathic person may decide and try to commit suicide, to disappear from this world.
Pasquale Garonfolo..............................I'm not sure if this dude is in the mental health field or if it is just his opinion. I remember reading some where that psychopaths and sociopaths are less likely to commit suicide.
