I agree with this interpretation. Men as a population have a higher baseline risk. They are already far more likely to die due to homicide (close to 80% of homicide victims are male) or misadventure than women. Also generally adhere less to a constellation of healthy lifestyle behaviors.

As you say, a woman who has undergone psychiatric evaluation for “severe crimes” and is categorized as highly psychopathic would probably diverge more from other women in those respects than a male counterpart, which would explain a higher relative risk of mortality.
