I know it may mess with ones head, as well as physical appearance, I'll look at it using the magic from ONCE UPON A TIME, if a person posses such magic as Twilights', they must have been chosen or became a dark one ( In Sci Twi's case, she was both at some point ). Now if you try to steal magic, you get destroyed, depending on what it is your soul may be able to pass on. So if the magic worked like in OUAT, then Wallflower would have died.
