Environment is the final step phase in the formation of a serial killer because how an individual interacts with their environment over time or in the present establishes behaviours and alterations in impulse control. How environment is the ultimate can be elucidated by applying a segment of Andringa et al.’s (2015) Rule of Conservative Change. The Rule of Conservative Change states there is the division of two modes of cognition; coping and co-creation. Coping mode is the defense and last-resort mode, and is essentially impulse governed and disregards morals. Coping stage in only accessible under stress, and is singularly focused on supposed survival, in the sense the individual does not think an acceptable standard of living is attained.
