The Walking Dead . . . Jim's still with Us

In Season 1, episode 4 or 5 I think, Jim gives up the ghost. In the previous night's attack he's bitten in the stomach and by end of episode the fever has taken him and he's standing upon death's door. He asks to be put outside, against a tree so he can feel the air before he dies. Rick is reluctant to oblige but does so at Lori's urging.

They leave  him looking at the afternoon sun. We are left with him there.

Of course we know he rises again and wanders the woods a terror to any living creature. I think they should ave just shot  him.
