Interesting possibility, but claiming psychopathy still reflects badly on a person's character, even if it means that person is almost certainly not a psychopath. It shows that a person is at least mildly histrionic and self-deprecating in an off-putting way (cheap, fake sincerity). Therefore, it's not a useful or skillful act, and the rational psychopaths aren't going to pursue it.
