I am a bit rusty on classic philosophy, but I think this dialog of Plato is beginnings of the debate between the categorical imperative of "do unto others as you would have them do unto you," and the utilitarian ethics of "do what will do the most good for the most people".
Actually, most ethicists (and I agree) don't like utilitarian ethics. For example, would it be ethical to kill Hitler? Well, once we knew what he was doing, and well after the fact, then maybe it would be ethical. But at the time he was actually carrying out his evil plans, few people outside of his regime knew just what he was doing, and so no one had the justification to kill him.
Further, what if by some incredibly small chance, Hitler changed his mind and decided to put a halt to his evil plans. What if he were the only one capable of doing it? What if killing him would have ensured some other even more extreme and effective Nazi leader would have taken his place and killed even more people than Hitler ever could have? If this were the situation, history books would have instead said, "if only Hitler hadn't died, so many people could have been saved, but at the time, no one knew of his sudden change of heart..." whatever.
It's hypothetical of course, but it shows why utilitarian ethics doesn't work, at least not as cut and dried as it appears to be on the surface.
The same goes for any bad guy, Saddam, Osama, or whoever. Sure it is incredibly unlikely that they will ever change their minds, and they deserve justice for what they have done. However, justice to the evil, and trying to prevent evil, are two separate ethical issues. Socrates said don't do evil for the sake of correcting evil, and for the most part I agree.
