Ok so this the semi short story. Roommate bought a ball python about 2 months ago from Petsmart. He (for convince) was about 12 inches long and refusedto eat. He was being offered thawed pinkie. My roommate brought the snake to the vet who force fed the snake. Now I didn't go with roommate but supposedly roommate was told to keep trying to feed the snake every other day. Now to me that sounds like a lot of stress on the baby BP. Also was supposedly told to force feed by giving 1ml of this paste that looked like pancake batter.

Now my roommates took a vacation and had a friend stop by every other to "feed the snake". Since I hate seeing an animal suffer, I looked up everything I could on feeding. The pinkie were the right size if not a bit small.

Now I know I am in the wrong for messing with another persons pet but I felt like I had to try something.

The next time their friend came over I recommended I try "force" feeding a warmed up pinkie.
I had watched videos and read few breeder's guides and a few mentioned that some young BP don't know the pinkie is food. also the videos showed techniques. I gently held the snake while I "booped" hit nose GENTLY. Third boop he opened his mouth and I plopped the pinkie in. I did not force it down, nor did I force his mouth open with anything.
Well He move around a bit then settled down, pinkie still in mouth. After about 3 mins he started to work the mouse down and soon it was swallowed.

Fast forward 3 days and the snake was still alive and active when held briefly.
Now fast forward 4 more days and my roommate says the snake is dead and it's my fault. First she said that the snake must of had a blockage and the pinkie killed it. 2 days later she is now telling me the BP had symptoms of a broken neck or jaw and that it was my rough handling that killed it. Now I know human medicine better but I doubt a snake with a broken neck or jaw would be as active when being held or let to explore (an arm and lap that is)
Now again I know the feeding without permission from the owner was incredibly wrong and was done with the best intentions. Also yes I know what they say about good intentions. I feel horrible that the snake died

What I want to know is if any of that sounds like I directly killed the snake, that my actions had a good chance in causing the snakes death or that the feeding and the snakes death happens to coincide. Also your opinion on the actual cause of death.
I feel guilty but being told "you killed my snake by breaking it's neck" is a bit harsh
