If I abandon a Christian worldview, I see no plausible reason - other than purely selfish reasons - to be a Moral person. In fact, [and I know this will be contraversial] but I believe that many of these crimes are strictly due to a lack of the Christian worldview, although, paradoxically I find that many Christians [?] engage is such activities. If Christianity is proven false, do what you wanna do, as long as you come out alive and on top, Who cares... pure Hedonism is championed. Does that answer your question?
