Comment: Kill  them if we must or kill them because we can. Big difference. When a bear is charging, do you shoot them. When he is biting your leg, do you shoot then? When the bear is smacking the eye balls out of your head, do you shoot them then? I can tell you from first hand experience many times over, you better shoot when he is charging and hope you kill him before he kills you outright with one swat or sends you to the hospital.
