What does genocide accomplish if god were to destroy 99% of the human race? If perfect angels disobeyed and rebelled against god, if perfect humans rejected god (Adam and Eve), what will killing all these "imperfect" humans accomplish? Won't the cycle just repeat over and over and over with god having to commit mass genocide every few thousand years to cull the dissident ones who can't get with the program?
Without even stopping to analyze the evidence against a moral god, I find the bible to be completely illogical.
