Though its all hypothetical, any bite could and should be viewed as any other like injury. Obviously no amount of medical procedures would have saved Dale. T-Dog was not only bitten once, but covered in zombies and eaten. Had he only been bit and the wound treated like any other normal non life threatening wound than he could have been aided and recovered. Had they had the proper medical supplied Jim could have been saved as well.
Carl when shot if he hadnt been treated would have died and turned, Merle if he had bled out would have died and turned. All serious injuries, yet treated and recovered.
Bites are no different than any other injury. If they are life threatening or not. If it can be medically treated regardless of the injury as if it happened by a zombie or by playing basketball in the prison yard it can be treated with measures, as they showed by treating Herschel. If a zombie bites your jugular and they cant get to you in time than yes you die due to being bitten... or you are bit and left you die. Bit and be treated if medically possible has been portrayed as possible and will continue to be.
