This. Absolutely.
Millard is a veritable bouquet of psychopathy. But IMO we don’t know enough about Noudga to say, and we know enough about Smich to say that he is almost certainly not psychopathic. Psychopathy is a particular confluence of multiple behaviours, not just a willingness to kill with an apparent lack of conscience.
If I had to guess, I would think Noudga definitely approaches clinical narcissism. But while every psychopath is a narcissist, not every narcissist is a psychopath.
