As for your other arguments, Beatrix held the stone containing Odin in the palm of her hand, it was completely harmless. She has no idea what the extraction process is like until she's seen it that's when she sees how harmful it is. WAIT A SECOND? Isn't that when she changes sides? Yes. Point. Done.
