Why Doesn't God Stop Evil?

While nearly everyone asks why God doesn’t stop evil, few people ask why God doesn’t stop pleasure.  Stopping pleasure would be an effective way of stopping evil while maintaining human freedom.  That’s because no one does evil for evil’s sake.  We do evil to get good things, such as money, sex, and power.  Take away pleasure and the incentive to do evil would vanish.  But if God were to stop evil by ending pleasure, would the human race continue?  If it did, would anyone like the pleasureless world that remains?
