God judges men from the inside out; men judge men from the outside in. Perhaps to God, an extreme mental patient is doing quite well in going a month without murder, for he fought his chemical imbalance and succeeded; oppositely, perhaps the healthy, able and stable man who has never murdered in his life yet went a lifetime consciously, willingly never loving anyone but himself may then be subject to harsher judgment than the extreme mental patient. It might be so that God will stand for the weak and question the strong.
As readers, we are seldom interested in the fine sentiments of a lesson learnt; we seldom care about the good manners of morals. Repentance puts an end to conversation; forgiveness becomes the stuff of moralistic tracts. Revenge - bloodthirsty, justice-hungry revenge - is the very essence of romance, lying at the heart of much of the best fiction.
