Pascal’s Wager is inherently flawed for a few reasons.
1. Belief in God is not based on a wager. You can live as a religious person and go through the motions, but doing it because of the wager is not true belief in God. If belief is required, not just the practices, it wouldn’t work.
2. The Wager works if the only thing required was belief in a God. However, there are many different religions, and many are mutually exclusive. If you really don’t know what is true and what isn’t, how could you pick a religion? If you pick Judaism, the Christians believe you’re doomed forever because you don’t accept Jesus. If you pick Christianity, the Jews believe you’re in trouble because you do accept Jesus. Multiple religions throws off the while premise of the wager. It only works when there is one belief that works across the board.
