And that is a good point... Pat Robertson might say the people who were at that movie were punished by God. Is he wrong? I don't believe he is any more 'wrong' than someone who thinks less violence in movies would have prevented this, or fewer/more guns in the hands of law-abiding citizens would have stopped it.
We can form all kinds of psychological 'comfort zones' on this, to help us cope with the horror of the tragedy. That is normal, and what people do. It helps you to deal with this by blaming (at least partially) the entertainment industry. Others cope with the shock of what they are witnessing on TV, by blaming guns and gun laws, because it gives them comfort to find something to help make sense of this. Again, that is a normal human psychological reaction when these things happen. If some wacko religious group had been protesting 'Dark Knight' and trying to prevent it from being screened because it was violent, you would have been livid last week. But today, you can see where there is irony, and you can see that we are becoming like the Romans. Do you see how quickly your perspective shifted?
Now let me make it clear, because I know pinheads have the tendency to completely misconstrue things I say... I am NOT arguing that lack of spirituality is the reason this tragedy happened. MY belief is, tragedies happen because people sometimes go off their rockers. That simple. We didn't do anything to cause this, there isn't some thing we could have done to prevent this, it's just a tragic instance of someone doing something senseless... we don't HAVE to make sense of it. The point I am trying to make with the interjection of 'spirituality and morality' is that people can use all kinds of comfort thoughts, that included. So when you run around trying to find the thing that you can blame this on in your mind to help you cope, remember that other people can do the same with whatever they find comfort in as well. It's part of being human, that's all I am saying.
Things like this are going to happen now and then. There is nothing we can do to prevent it, there is no 'reason' for it, or 'cause' behind it. It's not because we haven't gone to Church enough... it's not because we watch too much violence... it's not because we have legal firearms... none of that is the REASON this happened! IT HAPPENED BECAUSE SENSELESS ACTS HAPPEN SOMETIMES.
