As a character, Eddie is a serial killer who operates within the eerie confines of the psychiatric hospital where Rachel and Zack are trapped.

Ultimately, Edward “Eddie” Mason stands out as one of the most intriguing characters in Angels of Death.

Looking at his behavior and personality traits, it seems that Edward “Eddie” Mason may fit the ISTJ (Introverted, Sensing, Thinking, Judging) type in the MBTI framework. He often keeps to himself, suggesting a preference for solitude and introspection. His decisions are rooted in logic and observation rather than emotion, and he shows a strong sense of responsibility and discipline. Eddie also values order and structure, which becomes evident in how he approaches tasks and handles disruptions in his environment.

This personality type is often described as dependable and detail-oriented, and Eddie embodies these traits. He is methodical in his actions and holds others to the same standards he sets for himself, which occasionally leads to friction with other characters. His perfectionism and adherence to rules are key aspects of his behavior, and he visibly struggles when faced with unpredictability or disorder.

For Eddie, following these rules is not just about survival—it’s about creating a sense of control in an otherwise chaotic and frightening world.
