I've always thought this Lewis quote was particularly apt:

"But in general, take my advice, when you meet anything that’s going to be human and isn’t yet, or used to be human once and isn’t now, or ought to be human and isn’t, you keep your eyes on it and feel for your hatchet."

(Mr. Beaver, on the White Witch, from "The Lion, The Witch, and the Wardrobe")
