Life in this fallen world is to a great degree meaningless, our aspirations are constantly being frustrated, and sometimes the respectable people are oppressive and bigoted. And yet there is a Good that will triumph over Evil in the end. From a Christian perspective the problem with both kinds of stories is that they tend to blame problems on things besides sin and identify salvation in things besides God — and therefore are ultimately too simplistic.
Life changing repentance begins where blame shifting ends.
