All Religions are corrupt after about 100 years after the founder's death. However, you do not have to be an atheist to see that.
The religious are obsessed with death and the imagined after life, makes you wonder, are they so scared of it? Is their fear that god will somehow punish them because they didn't quite make the grade on earth? The jewish god in particular is a marvelous god. He creates humans, places them on this earth which is full of amazement, then roasts them in hell for eternity. Hey all you christians and jews, what if, just what if you were a failed follower of god. Ohhhhhhh mate, you're fucked. Now spend the rest of your miserable earth life worrying about that in a self created hell.
Christians and jews walk around earth dwelling on stuff like heaven, hell, god, punishment, devil, demons, burning lakes of fire. The agnostic or atheists you'll find in cafes, pubs, relaxing, having a drink, not a care in the world and certainly not dwelling on stupid religious nonsense. Which would you rather do?
