Why was eddy able to kill the shark but not thomas Hudson of bimini from islands in the stream by ernest Hemingway?

Eddy was able to kill the shark because he was able to quickly react and take action to protect himself. Thomas Hudson, on the other hand, was unable to protect himself from the shark due to his physical limitations and the circumstances surrounding the attack. Additionally, Eddy's experience and knowledge of the situation played a role in his ability to kill the shark.
