Depending on our choices and intentions, the amounts of joy and suffering for both us and other viewpoints varies.
I believe that Universe is continuously solving for the maximum sum amount of joy from all the viewpoints combined.
Of course, a certain amount of suffering is required to bring about the joy, whether by providing a comparison, or by carving our abilities and motivations.
When I set my intentions for maximum joy and follow through on them, the Universe "likes" and "assists" this in amazing and miraculous ways, which bring about even more joy, and so on.
We are truly fortunate to exist in a Universe which is set up this way.
