I also think everyone here needs to relax.
Knowing about the situation and advising the owner to take action is all IK can do. Lets be real here. This is a snake, even if they were to call ASPCA or something I doubt they would do anything about it. Best case scenario they would euthanize it. This is not a cute little puppy or kitty. :/
Obviously the snake should be seen by the vet. If the owner is too ignorant to take IKs advice, then that is that. We can't save them all.
There are most likely hundreds of ball pythons out there who die because of improper care, early breeding, or just plain negligence. A forum is not going to be able to save each and every one. Sometimes we just have to take our losses and provide support. It seems to me like this situation was inevitable. If the snake dies, it dies. Lets move on and stop blaming one another for what "should" have happened. There is nothing we can do about it.
We are all passionate about these animals. Questioning someones passion because they wanted to help a friend out is so incredibly wrong on so many levels. The main reason the OP came here was to HELP THE SNAKE. Whats that you say? Thats what you would like as well? What a coincidence!
We are all here for the same reason. Stop treating one another like monsters.
