The problem with killing this one was outlined in the article, and there are a lot of them that weren't discussed in the article. For one, it wasn't his to shoot. For two it wasn't his right to shoot it. For three there's plenty of caribou and moose out there that he could have put down instead of that lone bison, so he really didn't need to kill it. For four, it's illegal. For five, his people in the YK delta don't have any subsistence tradition relating to hunting bison, so he shouldn't have killed it. For six the State of Alaska, Wildlife Conservation Center, and the Federal Government put a lot of time, money, and effort into putting that bison out there, and it wasn't so some poacher could sneak out and fill his freezer.  Does that answer your question?
