To me it's a beautifully-written poetic exploration of a world without evil. For evil to exist there must be something else to compare it to. And there's nothing else in BM. It's just a mundane world of unceasing animal violence reduced to the quotidian. I imagine the inhabitants of WW II concentration camps might recognize such a world.
A world without evil is a much scarier place than one where the concept of evil needs to exist in order to contrast it with something else.
