Final answer:
Patients with pyromania set fires due to an impulsive need for gratification, not for monetary gain or to express a political ideology, which are strategic reasons not associated with the disorder.
Step-by-step explanation:
The symptom that would not be expected in a patient with pyromania is E. Setting fires for monetary gain or as an expression of political ideology. Pyromania is a psychiatric condition characterized by impulsive and deliberate fire setting, not for any external rewards, but rather for gratification or relief from tension. Key features of pyromania include a fascination with fire, tension before the act, pleasure, or relief when starting fires, or when witnessing or participating in their aftermath. Setting fires for monetary gain or ideological reasons does not align with the impulsivity and gratification associated with pyromania; these actions are more strategic and goal-oriented.
