Although her disobedience is tragic, Eve's innocence is not all bad. Certainly, that innocfence leads her to make a poor choice - the very worst - but the fact that she makes a choice at all, the fact that she engages the Devil in a debate which could go either way, the fact that she acts without God breathing down her neck - all speak for her free will or, what amounts to the same thing, her margin for error. It is from this margin for error that freedom springs, because you can't be free to right unless you can be free to be wrong.
