I own gun's lots of gun's I carry, both on my person and in my car. Are you a bad person for having that reaction? in a word No. Would I do it no but then again I can't access the threat level you might find yourself in that would cause you to make that decission. But being armed means that in every situation you're different than the people you're around. Because of that you have to have a different mindset than other's. Give you an example, two years ago I on accident cut a guy off in traffic, he get's all pissy pulls in front of me and at the next light gets out of his car and starts walking toward my car. I rolled my window down and appologized for it and was serious. He stands at the front of my car with my wife and new baby in it yelling and threating me telling me to get out of the car bla bla bla, but he never came past the headlight's. I kept my cool didn't move fast or raise my voice and kept a level head. To this day the guy never knew that he was standing less than 6'-0" from dieing on the cold asphault because of it, I never even put my hand on my weapon or reached for it, no need had he kpt walking and gotten to where he could get his hands on me I might have simply taken the weapon out and kept me hand on it while never even pointing it at him or letting him know I had it.
When you have the ability to end a life you have to do everything you can to not need to.
