Was the good guy with the gun really a good guy, or was this just another AR-15 murder spree?

4. He was

a legal carrier of the firearm. If he was a felon, he would not be allowed, and he would have been arrested and charged by the police on the spot for being a felon in possession of a firearm. That's a very serious crime.
The real truth is that in states that are "shall issue" or Constitutional Carry, probably at least 2-3 out of 10 people you pass on the street are carrying a concealed firearm. And more people than that at least have a firearm in the glove box of their vehicle. There is no motive to be assigned to someone for simply carrying a pistol for purposes of self-defense, as has been proven by this one incident alone.
People can be pro 2nd Amendment and still support reasonable gun control efforts, I am one of those people. And I insist that I be allowed to carry a defensive weapon if I choose to do so.
If you are searching for another motive, ask yourself why this 22 year old man had a gun on him, was in a mall full of people, and only shot one person, specifically the one who was trying to murder people. Did he keep shooting? No, he didn't. And there is the motive: he wanted to stay alive to see another day. I don't know about you, but I find no fault in that motive.
