The majority of it is the ravings of a half-sane murderer & his pursuers. I just don't like books that have that surrealist feel, and this one had lots of it. 
 It does not mention murder is against God's law. The Bible is mentioned a bit, but not that true forgiveness & redemption doesn't from others but from God. There is never true repentance to or acknowledgment of God, only theories that we must suffer for our sins. As all sin is against God, our suffering can not atone for us. Only accepting Jesus' sacrificial death can atone for our sins, great or small. 
 It may be a classic, but I didn't think it was that great.
