No, you are assuming that George is better with a gun then Bob. Its only in the movies are the heros does not get shot, even with a little army shooting at him.
the only reason for having a gun is to be able to point it at another person, and that is a bad reason.
No, the point of a gun is to shoot someone. If someone breaks into your house, do you honestly believe that person has only the best intentions for you? No; what's most likely, that person wants to either harm you or take your things or both. To stop that from happening, you point,
then you pull the trigger; this may or may not kill the person, depending where you shot, but it does a fine job at stopping a crime before you're a victim to it.
If you don't believe me, try doing anything after being shot in the leg, outside of crying and going to the hospital with a new lesson on breaking into someone's home. To say I'm only assuming, is to say, "You're only assuming the cancer treatment will make you better; it's only the movies the cancer patient gets better, even with his whole body ravaged with cancer."
Trust me, the treatment may not defeat your cancer, but it's better than no treatment at all.
