Following your logic, nothing good comes out of not having values / principles either. It's about how you choose to live your life in this world and what you choose to sustain on the way.
Maybe you don't get direct instant rewards for your good deeds but one thing is certain.. balance is part of the main principles of the universe. It's not all destruction and It's not all pink clouds either.. surf the grey zone on your own terms and remember that everything you see has many sides and functions. Not all is what it seems. Your choice is the trail you leave behind. That is why we adopt values and principles.
