I like Nietzsche for how he presents a grounded view of modern philosophy and urges us to be strong to face life, but having read him a lot, I don't like his views on morality. First of all Nietzsche wrote in twisting, digressing prose to make sure the reader made some considerable efforts before fully observing his works, so taking Nietzsche word-for-word will just be getting a vignette of his philosophy. Yes he criticised Christianity, with his famous quote 'God is Dead', for making men and women weak, but at the same time he saw it as an answer to nihilism - that in one way or the other European culture took Christianity to keep the populace from becoming nihilist. And his views on moral principles are duplicitous - like his treatises on morality gives a great philosophical distinction between good, bad and evil, but at the same time he made claims like Jew morality is bad, etc. And if you look at his principle of envy and "get what you want" coupled with his moral views, they eventually ended up inspiring Nazism (Steven Pinker makes a good argument for this). So in my opinion, envy without morality leads to a kind of "moral heresy" and Nietzsche never addressed it explicitly.
