Are there published testimonies from Christians with a diagnosed personality disorders like psychopathy about their experience of sanctification? Some personality disorders like psychopathy and antisocial personality disorder are considered by clinicians to be difficult if not impossible to treat. Wikipedia summarises the difficulties with treating psychopathy as follows:

Psychopathy has often been considered untreatable. Its unique characteristics makes it among the most refractory of personality disorders, a class of mental illnesses that are already traditionally considered difficult to treat. People afflicted with psychopathy are generally unmotivated to seek treatment for their condition, and can be uncooperative in therapy. Attempts to treat psychopathy with the current tools available to psychiatry have been disappointing. Harris and Rice's Handbook of Psychopathy says that there is currently little evidence for a cure or effective treatment for psychopathy; as yet, no pharmacological therapies are known to or have been trialed for alleviating the emotional, interpersonal and moral deficits of psychopathy, and patients with psychopathy who undergo psychotherapy might gain the skills to become more adept at the manipulation and deception of others and be more likely to commit crime. Some studies suggest that punishment and behavior modification techniques are ineffective at modifying the behavior of psychopathic individuals as they are insensitive to punishment or threat. These failures have led to a widely pessimistic view on its treatment prospects, a view that is exacerbated by the little research being done into this disorder compared to the efforts committed to other mental illnesses, which makes it more difficult to gain the understanding of this condition that is necessary to develop effective therapies.

Christians believe however that there is no class of person that is beyond the hope of the Gospel, and that when a person is united to Christ and indwelt by the Holy Spirit, God begins the process of their sanctification, which will be completed in the resurrection. Christians should therefore be increasingly empathetic people as God teaches us to love others with his overflowing love.
Personality disorders like psychopathy are characterised by reduced or in severe cases seemingly non-existent empathy for others. While we may not have developed any psychotherapeutic strategies for teaching those with personality disorders to genuinely love others, God can accomplish what is impossible for us. So I was wondering if there are any Christians who have been clinically diagnosed with a personality disorder like psychopathy or antisocial personality disorder who have written or given spoken testimonies about their experiences of the power of God to sanctify and transform their lives, and whether that sanctification has included an increased sense of empathy?
Here is the testimony of David Wood, a formally anti-social-disorder-diagnosed atheist turned Christian.
Here is a variation of his testimony given to an audience, in 23:30 he states his formal diagnosis as anti-social personality disorder made by the mental hospital he was put into.
