Damnit, someone should be! If a God exists, she should be doing all in her power to stop all bad things from happening to people. If I thought it would be productive, I'd pray for that.
Why?
If a God exists, why does it have to stop "bad" things from happening?
Usually, it is the case that bad things, or good things for that matter, are caused by something. They don't usually just happen spontaneously, in its purest sense.
For God to stop a bad thing from happening to someone, would mean that God would have to prevent the action of someone, or something else. This would introduce a bias on the part of one of protagonist.
Maybe i'm a little bit strange, but i don't really like the idea of divine bias... a tilting of the scales by an all-powerful (or near-all-powerful) being, feels a little off.
If we were created, wouldn't it be best to just let us be? I could be wrong here, but i feel that things usually just tend toward equilibrium - it may not be the direction we always like, but do we really know whether or not it really is a "bad" direction?
