Ethics include following the laws for the MOST part. You can't just simplysay that "ethics is obeying legalities," though! Ethics is more complex than that! For instance, legal calibers, weapons,baiting, even Sunday hunting, among other things, are legal in some states, illegal in others!
Ethics, parts with the law in some cases also, such as humanely finishing off a mortally wounded animal without having the proper tag!
As someone has said, ethics is more of a "personal" thing, its what you do when no one's looking! Apersonal code of conduct, and I believe that ethics doesinvolvesthat!
On the other hand, ethicsgoes beyond a personal code of conduct! Society, ethnic grouping, geography, religious/non-religious views. All of these things contribute to our moral values, and ourethics as a whole!
