Sometimes it certainly feels that way.   But I dont think it is necessarily unbalanced.    I do think evil and pain is necessary for the things we consider good.   The concept of Rhythm in the Kybalion is a good attempt to describe the way the balance manifests in a simplistic and accessible way.    God is playing games with himself though us, and the world as it is may be the best possible world he could create in order to achieve this purpose.   But he may be forever creating and destroying worlds because in the end, they give him no lasting pleasure.
