Bad in the sense that it is at it's core a denial that there exists something such as good, and even something such as bad — in almost every sense of the word, whether it be aesthetically or morally.

One of the core contentions of the Christian faith, is that there is something more abhorrent than doing something bad, and that is the denial that it is possible to do something bad. Yet, this is about the only article of faith for our modern insanity.
