Does anyone know what specific personality disorder(s) Alexander Pichushkin had?

I believe that the courts say he has no known personality disorder because they evaluated him and found none, however he though himself as "GOD" and dicho he chose which person would live and which would die, which many court officials say he showed no remorse for the killings and acted like he had narcissism and acted also like a "psychopath" because of the "cruelty" towards his victims. They also say he showed signs of having anti-social personality disorder as well, but as I dicho above, the courts found him of having no personality disorders of any kind.
