You are a prosecutor preparing a case. The facts of the case support a charge of either capital murder or first- degree murder, but you are not sure how you feel about the morality of the death penalty. You have asked for opinions from other prosecutors in your office. Later, Ted comes by and also argues in favor of seeking the death penalty. His point is that other would-be murderers in the community need to see that they face the ultimate penalty for committing murder. He presents you with research that supports the idea that the death penalty deters crime. He says "I can see why you're not crazy about the idea of putting someone to death-that's a terrible thing. But it's best for the whole community if it sends a message that prevents other murders." Ted's argument is based on:
A. utilitarianism. B. ethics of care. C. deontological ethics. D. ethical formalism.
