Wow, wonderful, extremely wonderful. I have watched this movie a countless number of times but still couldn't figure out what you just brought to my knowledge and understanding or should I say I was quite little then when I watched it that why I wasn't able to relate that much.
And this movie really teaches us something great just as you outlined, maybe if she had been exposed to evil, evil might not be able to overcome her. Indeed its a privilege to read and learning from you @honeydue, exactly adsactly has everything you're exactly looking for.
