They're not actually saying they're gonna kill it. It's a joke. Besides, if it actually is your last resort, and your other option is being mauled to death, you don't really have a choice
Actually that usually doesn't work unless you're a master marksman, it's much better to carry bear spray because it'll burn the hell out of any animal in that general direction, usually blinding them temporarily, making the attack more trouble than it's worth to them. You also don't have to kill the animal (don't get me wrong I'd kill it if there was no other way) and it instills a fear of humans that may prevent the bear from getting into anymore encounters with people. Also if you are hiking in bear country be sure to make noise (stepping on twigs, shaking a can of pennies, talking) as this will prevent you from surprising them and inciting an attack, most of the time bears will get the heck out of dodge if they hear humans coming. Sorry I'm being serious on a funny post, just thought it might be good info for those who don't already know. :b
