Psychopaths are notoriously difficult to treat. Most of the reason for this is that, by and large, they simply don't want to be cured. This isn't to say that they're enthusiastic about being psychopaths, but they don't see it as being problematic enough to be worth the trouble of changing. In other words, while they may not necessarily want to be psychopaths, they don't particularly want to be not-psychopaths either.

If you're actually worried about being a psychopath, then clearly you want very badly to be a not-psychopath. If it's that important to you, then you're missing one of the critical markers of psychopathy.
