Why? Because you agree with the madman?
Nietzche gloried in the sewer of self-worship and died there, a blithering, braying jackass.
The great enabler of Hitler prophesied his own cruel, surpassingly evil impact on the world through his vicious ideas. Though the boil is lanced, the poison is not drained yet.
A few more "thinkers" such as Nieztsche and the world will be left an inheritance to the cockroaches and blowflies.
Nitezsche was a punk, a well-written punk.
I've only read about what he wrote, so I'll have to take your word on his knowledge of St. Paul and the Law -- you're probably right, though. It's often true that those who "hate best" also make it a point to know the most about what they hate. (A good example being that certain class of "lapsed-Catholic anti-Catholics.")
I think Nietzsche's position is probably best described as a grand exposition of the logical end of atheism. The real beauty of his writings stems from his being on the ragged edge of insanity -- which made him immune to the shame and horror that prevents "lesser" atheists from taking their position to its ultimate conclusion.
