Those not of the elect serve the purposes which God wills- they are the example which we acknowledge as separate from what is good, serving as spectacles of wickedness. If you read the Bible, there's actually plenty on that- especially in relevance to the day of Judgement.
All that God is and all that God does, is done in perfect justice, mercy and righteousness.
If you don't believe that you need to get yourself another God, one that you can trust and believe in.
