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

[Incognito]

I'm going to quote Arno Dorian and Ezio Auditore here (Assassin's Creed)

"The Creed of the Assassin Brotherhood teaches us that nothing is forbidden to us. Once, I thought that meant we were free to do as we would. To pursue our ideals, no matter the cost. I understand now. Not a grant of permission. The Creed is a warning. Ideals too easily give way to dogma. Dogma becomes fanaticism. No higher power sits in judgement of us. No supreme being watches to punish us for our sins. In the end, only we ourselves can guard against our obsessions. Only we can decide whether the road we walk carries too high a toll. We believe ourselves redeemers, avengers, saviours. We make war on those who oppose us, and they in turn make war on us. We dream of leaving our stamp upon the world... even as we give our lives in a conflict that will be recorded in no history book. All that we do, all that we are, begins and ends with ourselves"

"Twenty-two years ago, I stood where I stand now – and watched my loved ones die, betrayed by those I had called friends. Vengeance clouded my mind. It would have consumed me, were it not for the wisdom of a few strangers, who taught me to look past my instincts. They never preached answers, but guided me to learn from myself. We don't need anyone to tell us what to do; not Savonarola, not the Medici. We are free to follow our own path. There are those who will take that freedom from us, and too many of you gladly give it. But it is our ability to choose – whatever you think is true – that makes us human... There is no book or teacher to give you the answers, to show you the path. Choose your own way! Do not follow me, or anyone else."

In a nutshell, I'm not going to waste my time telling you why you should become an Atheist. I'm an Atheist because there is no proof for any of the religions but that doesn't mean I'm immoral. If you believe that you need faith, go ahead, believe whatever the hell you want.
