Want To See The Logical Path Which Underpins Materialistic Philosophies? - Terrifying!

In his book The Gates of Janus: Serial Killing and its Analysis Ian Brady offered us a fascinating insight into his deepest beliefs. Inspired by the Marquis de Sade’s sadomasochistic writings Brady argued that atheism forces us to redefine our deepest moral beliefs. 

If God is dead then only 'nature' exists. And if only 'nature' is real then moral concepts of good and evil are as fictitious as the proverbial tooth fairy. For Brady and the Marquis de Sade pleasure is the only god we should serve. And murder is the supreme pleasure.
