Final answer:
Julian's behavior of trying to rob the drugstore can be attributed to the dominance of the id component of personality according to Freud's theory.
Step-by-step explanation:
According to Freud's theory of personality, Julian's behavior of trying to rob the drugstore can be attributed to the dominance of the id component. The id is the primitive and instinctual part of the personality that is driven by unconscious desires and seeks immediate gratification without considering the consequences or moral standards. In Julian's case, the id was overpowering the ego and superego, which would have acted as internal controls to prevent him from engaging in such behavior.
