I haven't read all the way through this thread, but I've seen enough...I thought this was a rather straight forward question. My opinion is simple, if the animal manages to eat, drink, poo, and move to thermoregulate, then it should be allowed to survive. A lot of animals can live with slight deformities without being in constant discomfort. Someone was saying if they should put a ball python down for missing an eye, or for having a skin blemish, to me this wouldn't even be a quetion. Some breeders or collectors may not want to buy a snake like that, but I would, I think it gives the animal some character...
It is sad when people start caring more about the money they make than the snakes they produce....
