Final answer:
Joe's internal debate about stealing reflects Social Control Theory, as his adherence to societal norms and fear of consequences prevent him from engaging in deviance.
Step-by-step explanation:
The scenario with Joe considering stealing from a coworker but deciding against it because he knows it's morally wrong is an example of Social Control Theory. Social Control Theory posits that deviance occurs when an individual's bonds to society are weakened or broken, and that people conform to societal norms because of the strength of these bonds. In Joe's case, it is his internalized belief in moral norms and the potential consequences from society that prevent him from committing the deviant act of theft.
