Ok um I am obviously a female by my user name but I would NEVER pay for that snake. I would take it off their hands if I had the room and try to educate them for future instances, but I would never encourage them to keep doing this to future snakes by making a pity purchase. I'm also an avid betta fish lover and have done a lot of research and plan to breed them in the future. I go to petshops and see them mistreated all the time and on the verge of dying. I refuse to buy those fish. Doesn't matter what animal it is, whether it be a cat, dog, horse, whatever I would never pay for a sickly, mistreated animal. All they care about is the money so why would I give them money to do it to the next animal? You've gotta think about the broader picture.
And the whole thinking with your heart and not your head really grinds my gears. It's the reason things like horse slaughter plants getting shut down happen. That's a whole different debate but with the same principle. You've gotta put logic before your feelings, because when you don't the animals suffer for it.
