That's funny. I had an "aggressive" baby normal ball python. He certainly didn't add anything to my bank account. I eventually took the time to tame him out. Still have him. I knew what I was getting into when I got a snake (a non-domesticated animal) as a pet. If I had wanted mr cuddles, I would have stuck with just my cat.
I may be totally off here, but you sound to me like the type of person who buys a high energy dog, like a husky or border collie (because they look good), then neglects to give it enough exercise, then surrender the animal to a shelter because it tore up your baseboards out of frustration/boredom.
-still the proud owner of a now tame normal ball python. And a few other balls, who have never contributed anything to my bank account.
