Atheists, tell me, a Roman Catholic: why should I become an atheist?

I think you can certainly have negative consequences. Your judgement is impaired and your morality compromised by always having to consider your dogma. In more extreme cases, you have people refusing treatment because they "trust in god" and such. So it's akin to a false confidence from alcohol, I suppose. A lack of responsibility, because you think an invisible man will make things okay.
