Why is the world a mess and getting worse? There are many causes, but I think the main one is the collapse of morality since WWII, those war years being 'anything goes' in so many ways. The orgiastic bloodbath to end bloodbaths still haunts us. The slaughter is still incomprehensible. 100m? How could Christian Europe allow such a horror, culminating in a genocide of European Jews?
At least part of the answer can be found in the critical years between the death of Jesus in 30AD and the death of Paul (67AD?), the man who replaced him at the heart of the new Jewish messianic movement that Paul's followers would call Christianity.
