Why Does God Allow "Evil" ?

The recent hurricane Katrina has brought this question to the surface once again and quite frankly I am disappointed at the answers given by some revered Christian leaders to this question. This is the answer I have heard again and again, it goes something like this, "we don't know we just have to trust God". I agree that we have to trust God but the Bible is very clear on why there is suffering and to say that it's not is a flat out lie. Here is the answer that should be given,Who are thou oh man that you reply against God? We deserve Hell for eternity and any thing less than that is an incredible mercy. How is it that we every day shake our fist in the face of God and then seem baffled when he allows something bad to happen to us? We must stop calling what God chooses to do, evil. Hurricane Katrina was absolutely just and right. But you will say,"What about the good people who suffered?" There is none good no not one; even Christians who suffer though they have much in which they can have joy and hope and the suffering of this world is not to be compared with the glory which is to come, still must say it was well deserved. Ever since the fall we as humans have been questioning the goodness of God. This kind of questioning is sinful and devilish and must be seen in that light and denounced.
