On second thoughts (after reading more about the subject) I have to admit that Rawat could be suffering from a narcissistic personality disorder. Sociopath is not an accepted term by the psychiatric establisment."Narcissistic personality disorder (NPD) is a personality disorder that is characterized by extreme feelings of self-importance, a high need for admiration, and a lack of empathy. NPD can be considered as a pathological form of narcissism. It is estimated that 0.7-1% of the general population are afflicted with NPD. Most people with NPD (50-75%, according to the DSM) are men.
NPD is often diagnosed with other mental health disorders (comorbidity) — or with substance abuse, or impulsive and reckless behaviors ("dual diagnosis")."
(I compared Wikipedia's entry with another encyclopedia and it is quite accurate)
