I'm not against Karma in stories. Mind you, I don't believe in Karma, but I accept it as a storytelling mechanism. But things with karma don't get more horrific, if anything, it lessens the horror because "I'm a good person, so that won't happen to me". Innocent people dying in horrible ways is more horrific, at least to me.

But as I said before, horror is subjective. I've given this particular story a lot of thought and... it just doesn't scare me. And no matter how much I ponder on it, I can't make the story scare me. I don't know if its my personal experiences or something. But it just doesn't work for me.
