Norm's avatar was not killed. It was wounded. I have seen the movie four times. It was only hit once on the shoulder. When the avatar passes out, Norm leaves his tanning booth and most likely goes off to heal his avatar. -Edit: Seeing that Norm carried a gun in his hands and didn't seem to have any form of medical kit on him, it's safe to say that he thought it was hopeless to try and repair the Avatar. Also, his Avatar never makes a return after that, and it's safe to assume that it was damaged beyond repair by one of the SecOps soldiers as the ground forces progressed through the forest. I'd like to think that he'd use his Avatar at Hell's Gate when the surviving RDA people leave. What do we see in that specific scene? A human Norm Spellman. Not his Avatar.
