EC already existed in a vague area to begin with; I don't see a problem with moving this thread and sub-consequent threads to the "Everything Else" forum.
I agree that quantifying 'mental corruption' is difficult and may not always fall into the realm of traditional TF or process. However, that is definitely a form and even a base of EC.
"Becoming evil" and suddenly presenting oneself as some garish whore aren't exactly analogous concepts, but contextually applying that behavior to a pure-as-snow heroine or an innocent teenager does fit in my opinion.
EDIT: Okay, yeah, "innocent teenager" may have been a poor choice of words there.
