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

[Pat Mustard]

All I'll say is that when I was having serious doubts, I prayed to God to show me in a way that I would know for sure that he is real.  Now some 16 year later nothing has ever happened.  So I can safely conclude that either:  A.  God doesn't want me to believe in him, or B.  God doesn't exist.

This is were Pascale Wagar argument kicks in.

Where are you going to place your bet?If you place it with God, you lose nothing, even if it turns out that God does not exist. But if you place it against God, and you are wrong and God does exist, you lose everything: God, eternity, heaven, infinite gain. "Let us assess the two cases: if you win, you win everything, if you lose, you lose nothing."~Peter Kreeft

Pascal's wager fails because it assumes a specific god exists and that everone will worship him. It doesn't give any latitude to other faiths or to a lack of faith either.

And if by chance you've picked the right god to pretend to worship, do you think it'd be that stupid or vain to fall for a bit of mummery?
