Final answer:
Batman's decision to take the blame for Harvey Dent's actions demonstrates Consequentialist reasoning, specifically utilitarianism. Harvey Dent, meanwhile, upholds a deontological ethical position by adhering to moral rules regardless of outcomes.
Step-by-step explanation:
In the final segment of the film, Batman exhibits Consequentialist reasoning by choosing to take the blame for Harvey Dent's crimes, believing that preserving Harvey's image as a hero will serve the greater good of Gotham. Batman's actions align with Consequentialist ethics, particularly utilitarianism, which holds that an action is morally right if it produces the greatest good for the greatest number, even if it entails personal sacrifice.
On the other hand, Harvey Dent appears to affirm a deontological ethical position. His view is that there are certain moral rules or duties that should not be violated, regardless of the consequences. This is evident in his actions and sayings throughout the film, where he insists on following the law and upholding justice, even if the outcomes are not the most favorable for everyone involved.
