IMHO, TacoTiki, you were correct to eject the bearer of abysmally bad energy!

Cards are cards. We all have our favorites and our preferences, but in the end they are simply a tool. They do not change the energy of the individual handling them, and their energy is not altered by that party, either. If it were so, how could you be expected to sell this deck after it had been in HER possession? She would have rendered the deck damaged goods! There is such a thing as being TOO nice. Under the circumstances, she fell victim to my beloved GIGO principle-garbage in, garbage out. I believe you did the right thing.
